How many BTU's are there in MLBs of steam?
There are 1078.9 BTUs.
What is the difference between steam turbine and water turbine?
The difference is that geysers are way much hotter than the steam from hot springs. The geysers can give you 3rd degree burns. But so can the steam from hot springs if you're in there to long.
Why mostly steam is used to rotate a turbine?
The Rankine cycle is one where a closed loop containing water/steam is used to transfer energy from an energy source such as a coal fired furnace or a nuclear reactor to a steam turbine/generator. It is the way all such power plants work, but not plants using gas turbines or combustion turbines which don't use a water/steam circuit. In the Rankine cycle there are progressive stages: 1. Cool feedwater is pumped at high pressure into a boiler which is heated by the furnace or nuclear reactor 2. The water is heated and evaporated at high pressure, becoming steam 3. The steam is further heated to become superheated 4. The steam is admitted to the HP end of the steam turbine, and it progresses in stages to the LP end by which time it is cooled and under vacuum (the vacuum is maintained by external cooling water and increases the efficiency considerably by getting the maximum energy out of the steam) 5. The steam condenses in the turbine condenser under vacuum, to produce cool water, and hence back to stage 1. Electrical energy is extracted by the generator which is coupled to the shaft of the turbine, but that is not really part of the Rankine cycle, which is described in thermodynamic terms only. See link below for more reading and diagrams.
How many btu per steam?
One pound of steam contains approximately 1,200 BTUs (British Thermal Units) of energy. This value can vary slightly depending on the pressure and temperature of the steam, but it is a standard approximation used in calculations involving steam systems. For more precise applications, it's important to consider the specific enthalpy of the steam at the given conditions.
What relationship exsists between turbine and generator?
A turbine is powered by such things as steam, burning gas or oil, water, or wind. The turbine is a type of engine, which might be thought of as a more efficient choice than a gas engine or reciprocating steam engine for doing the same job. The turbine could do many things ranging from powering a vehicle such as a helicopter, a ship, a locomotive, or a piece of equipment such as a centrifuge, a pump, or a generator. When a turbine powers a generator, the generator makes electricity.

How many BTUS in 1 pound of steam at 212 degrees Fahrenheit?
One pound of steam at 212 degrees Fahrenheit contains 1150 BTUs of energy.
How many btus are required to change five pounds of ice at 20 degrees to steam at 220 degrees?
6,520 Btus
How many btus does it take to turn water into steam?
It takes approximately 970 BTUs to convert one pound of water at 212°F (100°C) to steam at the same temperature.
How many BTUs will a 10-kilowatt heater produce if operated for 1 hour?
A 10-kilowatt heater produces 34,120 BTUs per hour.
How many btus are required to change one pound of ice at 20 f to steam at 220 f?
It takes approximately 144 BTUs to change one pound of ice at 20°F to water at 212°F, and an additional 970 BTUs to change the water to steam at 220°F, for a total of 1114 BTUs.
How many stages of steam turbine rotor?
It depends upon megawatt of turbine & design of blades.
How does a steam engine differ from a steam turbine?
Technically a steam turbine is a particular type of steam engine. A classic steam engine usually refers to a reciprocating steam engine, which uses a piston and crank arrangement, where pressurised steam (from the boiler) forces the piston through its stroke, producing output power. A steam turbine produces power with pressurized steam expanding to high velocity, and impinging on turbine blades which produce rotational output power. A steam turbine can be considered similar to a windmill, although steam turbines typicaly rotate much faster, and often have many stages of steam expansion within a single machine.
How many types of value used in steam turbine?
The types of values used in steam turbine range from 10 to 30 deg.of which 12 to 20 deg. are more common.
How many BTU will it take to change 10 pounds of ice at 20 degrees to steam at 220 degrees?
To change 10 pounds of ice at 20 degrees Fahrenheit to steam at 220 degrees Fahrenheit, you need to supply enough energy to first melt the ice, then heat the water to the boiling point, and finally convert it to steam. This process requires approximately 180 BTUs per pound of ice to melt it, 180 BTUs per pound of water to heat it to the boiling point, and then 970 BTUs per pound of water to convert it to steam. So, for 10 pounds of ice, the total BTUs required would be around 18,300 BTUs.
How many btus are required to change 5 pound of ice at 20 degrees Fahrenheit to steam at 220 degrees Fahrenheit?
To change 5 pounds of ice at 20°F to steam at 220°F, you will need to go through multiple phases: raise ice temperature to 32°F, melt ice to water at 32°F, raise water temperature to 212°F, and then convert water to steam at 212°F to steam at 220°F. The total heat required, in BTUs, is around 503 BTUs per pound of ice, which translates to about 2515 BTUs for 5 pounds of ice.
How many btu per hour would be produced in a 12-kW electrical heater?
There are at least 5 different definitions for slightly different BTUs. One of them says that 1 kWh = 3412.14 BTUs. Let's use that one. 1 kWh = 3412.14 BTUs 12 kWh = 40,945.68 BTUs
