Why was the steam train invented?
To get from point A to point B faster and safer
n the 1820s the port of Baltimore was in danger. The threat came from the newly opened Erie Canal (see "Traveling the Erie Canal, 1836") and the proposed construction of the Chesapeake and Ohio Canal that would parallel the Potomac River from Washington, DC to Cumberland, MD. These new water routes promised to provide a commercial gateway to the West that would bypass Baltimore's thriving harbor and potentially hurl the city into an economic abyss. Something had to be done.
A Modern Reconstruction of
the Tom Thumb
The local entrepreneurs looked across the Atlantic to England and found an answer in the newly developed railroad. In 1828, the Maryland syndicate, led by Charles Carroll - a signer of the Declaration of Independence - broke ground for the Baltimore and Ohio Railroad. The railroad's objective was to connect Baltimore with the Ohio River and the West. Initially, the railroad's power was to be provided by horses. However, it soon became obvious that animal muscle was no match for the long distances and mountainous terrain that would have to be traveled. The solution lay with the steam engine.
By 1830, the B&O Railroad had extended its track from Baltimore to the village of Ellicott's Mills thirteen miles to the west. The railroad was also ready to test its first steam engine - an American-made locomotive engineered by Peter Cooper of New York.
It was a bright summer's day and full of promise. Syndicate members and friends piled into an open car pulled by a diminutive steam locomotive appropriately named the "Tom Thumb" with its inventor at the controls. Passengers thrilled at the heart-pumping sensation of traveling at the then un-heard speed of 18 mph. The outbound journey took less than an hour. On the return trip, an impromptu race with a horse-drawn car developed. The locomotive came out the loser. It was an inauspicious beginning. However, within a few years the railroad would become the dominate form of long-distance transportation and relegate the canals to the dustbin of commercial history.
What is 'consume their own smoke'relating to steam carriages during the 1860s?
Answer Steam engines would have water heated in large tanks and then the steam that was created was harnessed and used to power the engine. I believe this is what this means by "consuming their own smoke." Hope this helps.
Where was the steam train invented?
In 1784, William Murdoch, a Scottish inventor, built a prototype steam train.
The first full scale working railway steam locomotive was built by Richard Trevithick in the United Kingdom.
Richard Trevithick (13 April 1771 - 22 April 1833) a British inventor, built the first full-scale working railway Steam Locomotive. On 21 February 1804 the world's first railway journey took place as Trevithick's unnamed steam locomotive hauled a train along the tramway of the Pennydarren ironworks, near Merthyr Tydvil in Wales, Great Britain. George Stephenson (9 June 1781 - 12 August 1848) a British civil engineer and mechanical engineer who built the first public railway line in the world to use steam locomotives and is known as the "Father of Railways". Trevithick invented the first train, Stephenson the first public railway line. **Early prototypes of Locomotive were built such as Scottish Inventor William Murdoch 1784.
How do the profile of sprocket teeth change as they wear?
the circular profile at the bottom becomes elongated with wear, and "hooking" occurs at the top
Who invented steam engine to power other machines?
Many people have invented devices called "steam engines" that powered other machines. The inventor of the modern steam engine operated from the pressure of steam was James Watt. He had been asked to repair a failed Newcomen steam engine that was used to drive water pumps to keep a mine dry. The Newcomen steam engine was actually a vacuum engine operated by injecting steam at atmospheric pressure into a cylinder then condensing it to create a vacuum by spraying cold water into the cylinder. Watt recognized both the issues of alternating thermal stress and low efficiency of this design. He proposed to the mine owners instead of repairing the existing failed Newcomen steam engine with one of his own design. Since then all steam engine designers adopted variants of James Watt's steam engine.
Was the steam engine popular in the victorain times?
Not so much "popular", any more so that modern prime-movers, but a necessity whether as stationary engines driving factory machinery, water and sewage pumping-stations etc; as railway locomotives of course, on the roads (traction-engines), and powering ships.
Where and when was the first steam locomotive invented?
It was built in Britain in 1804. The first public railway for steam locomotives in 1825.
How steam locomotive cause air pollution?
The combustion of wood & coal in steam engines produces carbon dioxide.And Carbon Dioxide makes the air polluted because most living things need oxygen to breath not carbon dioxide.
Can steam generate through hot oil running in steam boiler?
There are boilers designed to heat mineral oil (as well as other fluids) which is then pumped through a heat exchanger to generate steam.
Block diagram of two stage steam engine?
You can't give diagrams on a basic text-editor like this one!
To explain for reciprocating engines:
A "Two-stage" steam-engine is properly called "compound", and consists of 2 cylinders each with its own piston, piston-rod, crosshead and connecting-rod linked to the single crankshaft.
The "live" steam at high-pressure (from the boiler via the throttle-valve or regulator, and superheater) is admitted to the first cylinder and partially expanded during its working stroke there. On exhaust it is the sent to the second cylinder and expanded further.
The steam is thus expanded through a much larger pressure-gradient than would be the case in a "simple expansion" engine, hence obtaining the maximum practicable power from each does of steam. The only other way you can do that is to use an unfeasibly long cylinder, since steam expands roughly hyperbolically, according to the Gas Laws: pressure X volume = a constant.
To compensate for the steam in the second cylinder being at a much lower starting pressure, that, the Low-pressure Cylinder, is of larger diameter than the High-pressure Cylinder, to equalise the force acting upon both pistons. Larger engines were also built, with an interposed Intermediate pressure Cylinder (Triple Expansion), and some of the largest had a fourth cylinder still. The effect is the same - obtaining the most work from a given quantity of steam.
Incidentally you sometimes hear people describe compound engines as using "the same steam twice". That is wrong, but even professional traction-engine drivers and the like in the late-19 / early-20C held this misunderstanding.
The steam-turbine.
A steam-turbine is a form of compound steam-engine, though rotary not reciprocating, because it expands the steam from inlet to exhaust through the blades on a series of progressively larger discs along the rotor.As pressure falls along the series, the disc radius increases to equalise the torques produced by each disc.
What is the meaning of anchor point in terms of steam turbine?
I would suppose the "anchor point" would be the point where the turbine is firmly mounted to its base. The steam inlet, or steam chest, of a turbine is bolted to its foundation firmly, but the exhaust end of the turbine is mounted on sliding feet which allows it room to expand as it heats up. Often multiple casing turbines will have anchor points, or solid mountings for each casing section, and flexible couplings between each shaft section.
First american to invent the steam engine?
Thomas Savery from England invented the first commercially available steam engine.
Are steam engines and steam turbines the same thing?
Usually no, a steam engine usually refers to a system using steam pressure to make pistons in cylinders slide, while a steam turbine refers to a system using steam pressure to make turbine blades spin. However "steam engine" is often used loosely to refer to either.
What du you understand by the term governing of steam engine?
A governor is a speed control device. It can be mechanical, hydraulic, pneumatic or electronic. It maintains a specific speed of rotation of the flywheel of the engine, or the shaft of a turbine, which is set by the operator. Governing an engine is just that, controlling the speed of the engine.
Marquis Claude de Jouffroy d'Abbans in 1776. He built a paddle wheeler in 1783.
In the US, John Fitch built a steam ship in 1787. Robert Fulton built the first commercially successful steamboat in 1807.
What type of combustion engine in the steam engine?
A steam engine is an external combustion engine. As the steam engine combusts outside of the engine itself.
Why are marine steam turbines kicked astern first?
Dont understand the term "kicked astern first" First,--before starting or as part of the warming through process before use.
Perhaps you could expand on the question.
What did the use steam engines for?
They used them either for traveling or for supplies. E.g. Taking coal to the town for the villagers. Hope I helped :)
Where is bank 1 on the O2 sensor of a 98 Ford Ranger 4 cylinder engine?
"bank one" is misleading on a four cylinder engine, since there is only one bank to begin with. Bank 1, sensor 1 is the upstream O2 sensor screwed into the exaust system before the catalytic converter. Bank 1 sensor 2 is screwd into the exaust system downstream of the catalytic converter.
That code is manufacturer specific...I would need to know the vehicle information.
