What is the difference between steam turbine and water turbine?
turbine is driven, engine drives. in reality nothing, both use steam pressure to create a desired output. motion, turbine has 1 moving part that spins on it's axis. engine has many moving parts spinning an axis (crankshaft) I really feel there is a huge difference in the way the two power generating sources work. The turbine uses steam at higher pressures and in my view less efficently than a closed piston power source does. lower pressures can be used in the closed piston type engine and levels of output can be changed by simply adding more cylinders or expanding the diameter of the piston,there are more moving parts than a turbine but if you figure in the steam adjust valves probally not that many more. I have never understood why an turbine is used as opposed to closed piston type engine. Thank you. _____________________________________________________________________ A turbine opperates in a way similar to either a jet engine, or an old water-wheel. In either case, a steam turbine converst the thermal energy of the steam to rotary mechanical energy much more efficiently. An engine (either a single set like a locomotive, or a block like a gas or diesel engine) uses both the pressure and the expansive poer of the steam to move a piston. The piston is connected to a rod which connects the backand forth motion of the piston to the rotary motion of the crankshaft. A turbine is most fuel efficient in situations where full power is used most often, such as a powerplant, where the tubine spins a generator. An engine is most efficient in low-speed, high torque applications, such as a pisotn set coupled to the drive wheels of an old steam locomotive. The steam produced for a steam engine drives a piston up and down or left to right, while the steam produced for a steam turbine turns the turbine itself.
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 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 Btus of heat are removed per hour when the water at a flow rate of 10 pounds per minute is cooled 15 degrees Fahrenheit (Water weighs 8.33 pounds per gallon)?
To calculate the BTUs removed per hour, use the formula: BTUs = flow rate (lbs/min) × temperature change (°F) × 1.0 (specific heat of water). First, convert the flow rate to pounds per hour: 10 lbs/min × 60 min/hour = 600 lbs/hour. Then, calculate the BTUs: BTUs = 600 lbs/hour × 15°F × 1.0 = 9,000 BTUs/hour. Thus, 9,000 BTUs of heat are removed per hour.
How many BTU is 5021 MBH?
To convert MBH (thousand BTUs per hour) to BTUs, you multiply by 1,000. Therefore, 5021 MBH is equivalent to 5,021,000 BTU per hour.
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 is 125 mbh boiler?
A boiler rated at 125 MBH (thousand BTU per hour) has an output of 125,000 BTU per hour. MBH stands for "thousand BTUs per hour," so to convert to BTUs, you simply multiply by 1,000. Therefore, a 125 MBH boiler delivers 125,000 BTUs of heating capacity each hour.
