What is the formula of calculating boiler capacity through heating surface?
hi i am kashif iqbal, u asekd that how can we calculate the capacity of biler through heating surface its a very simple for example a boiler having heating surface of = 1425 sq ft applying thumb rule = 1425/260=5.48 tons
Where is number 1 piston on 1967 289 engine?
Passengers side front cylinder on engine is #1.
Passengers side front cylinder on engine is #1.
What is the working principle of mechanical seal?
*Invisible leakage
*Less friction/power loss
*No to little wear on the shafts or sleeves
*Flexibility - to accommodate shaft deflections and "End Play"
*No period maintenance
*Long Life
In practical use, the basic rotating face mechanical seal principle is adaptable to serve a tremendous number of sealing needs: standard mechanical seals can suit most requirements-including temperatures to 500 degrees F and shaft speeds to 3600 RPM through the choice of secondary seal and the combination of seal and seat face materials which are offered. Seals can be ordered in balanced configurations to seal pressures above 200 psi, or used in a multiple for extremely high pressures or especially severe fluid services....Special mechanical seals can be furnished to meet the most demanding of industrial applications considering pressure, temperature, speed or fluid.
Did a black man invented the steam engine?
No. The first steam engine was that of Hero of Alexandria, a Greek living in Egypt. The first practical steam engine was invented by Thomas Savery, an Englishman.
I suspect this is one of the many hundreds of "facts" promulgated by Black History Month that wildly overstate the contributions that black people have made to technological progress (for example, claiming that a black man "invented" something when what he really did was make a small improvement to an existing device). Such claims only serve to dilute the realcontributions by black people.

What is a gas turbine compressor bleed valve?
Valve which is meant to siphon off a portion of the flow from another system.
A heavy-duty gas turbine employs compressor bleed valves to protect the axial compressor during start-up and shutdown against stalling and surging conditions. These valves are typically only open during acceleration to rated speed and deceleration from rated speed. Newer heavy-duty gas turbine with complex combustion system arrangements designed to limit emission of harmful gases also employ the compressor bleed valves during very light loading to limit the amount of air entering the combustor.
Compressor bleed valves discharge into the gas turbine exhaust duct. Compressor bleed valves are generally closed during normal operation (with the previous exception) since "dumping" axial compressor discharge into the exhaust reduces efficiency (but it's MANDATORY during start-up and acceleration to protect the compressor!). Compressor bleed valves are generally either fully open or fully closed; they are not modulated.
Heavy-duty gas turbines also employ inlet bleed heat valves to recirculate a portion of the axial compressor discharge back to the inlet of the axial compressor for a variety of functions. One application uses them to heat the inlet air to prevent icing on the compressor inlet (appropriately called anti-icing protection); another application uses inlet bleed heat to protect the axial compressor when the IGVs (axial compressor Inlet Guide Vanes) are closed below the "normal" operating conditions ("normal" being before complicated combustion systems designed to limit exhaust emissions were invented).
Inlet bleed heat control valves are modulated to control the amount of air recirculated back to the axial compressor inlet. Recirculating axial compressor discharge back to the inlet is also inefficient, but is generally limited to approximately 5% of rated air flow through the compressor--and necessary to protect the compressor at low IGV angles. Inlet bleed heat valves are generally closed before the unit reaches rated load (except for anti-icing protection) and should be closed during rated power output (Base Load) operation (except for anti-icing protection).
Is pressure after throttling is more or less?
You cannot increase steam pressure through a valve without adding heat to it. Throttling steam always reduces its pressure.
How is steam used for propulsion?
another word for propulsion is or can be forward.it can be forward because propulsion makes something move forward
What was the name of the Victorian steam engine?
Which one? A large number of Victorian manufacturers built many thousands of steam-engines of all types and sizes between them! Most had no individual names, but had type-names, maker's / brand names and serial numbers. The only specifically-named engines were railway locomotives.
What is the function of steam traps?
The purpose of a steam trap is to stop steam from passing beyond its point of use. A steam trap performs two functions. One is that it is an air vent. Two, is that it is a water outlet valve.
Does a steam engine produce noise?
Yes, they do. They are, comparatively, much quieter than other machines, but they do make noise.
**BTW: Steam turbines (radial, axial or tangential steam engines) make a very loud high pitched noise, in most applications, because the steam passing through most steam turbines exceeds the velocity of the sound barrier, the noise is a continuous "sonic boom".
Are steam engines still being used?
Steam engines presently produce more power than all other types of engines combined. Most steam engines take the form of the steam turbine engine. The steam turbine is responsible for generating about 86% of the electric power used on this planet.
Reciprocating steam engines are still in use for limited applications, but are generally considered obsolete. Steam engines, either the piston or turbine type were used on most big ships until recently, and there are still a few steam locomotives about.
Where did James Watt refine the steam engine?
Principally when he was the business partner in the engine-building company, Boulton and Watt, in the English Midlands city of Birmingham.
What do you mean by cyinder in engine?
The cylinder, is the body of the engine that has been bored out in order to place a piston inside of it. The piston rides inside the cylinder.
Distinguish between First Angle Projection method and third angle projection method?
right side view draw in left side and left side view draw in right side is called third angle projection
designed a steam engine that was 40% more efficient, half the size, and significantly cheaper than standard steam engines.
While not a moving part, except with the Railway Locomotive, the Boiler assembly forms the bulk of the weight of the locomotive, more than the engine proper or drive wheels, valve-gear , etc, Long Time (since l974 seriously) Railroad Buff. I have managed two steam cab rides, but hundreds of Electric sessions on the GG-I
How does shower steam actually work?
It is not completely clear whether one is wanting to know what a steam shower will do for someone or how these physically work. A steam shower produces steam that is both soothing and exhilarating. The way it works is through a steam generator that heats water to a boil and then releases hot vapor to fill the stall with moisture. This has proven to be very good for skin and sinuses.
Sorry. We do not know what kind of hand tool you are talking about. But there are lots of hand tools that were invented. name a hand tool and i bet we could tell you the history of it.
How did the steam engine affect daily life?
Talking of their effects on 19VC life: Stationary steam-engines drove factory machines proving a lot of employment. They were used to power water & sewage pumping stations, in the drive to improve public health; and later, especially once the steam-turbine became established, to power alternators for public electricity supplies.. On the railways, steam locomotives could haul freight and passenger trains reasonably swiftly in either local routes or over great distances. Used in ships, steam power meant far more rapid transport, far more reliably and safely than under sail whether along rivers or across the oceans. It's important to realise it was not so much the engine being steam that mattered, as it providing for the first time in history, a machinery power-source that could be made in large quantities, suitable for the purposes and not dependent on natural forces like river-flow or the wind.
