How do you calculate only turbine efficiency not turbine cycle efficiency?
by calculating the inlet steam enthalpy-outlet steam enthalpy we will know the total kcal consumed for output mw required kcal for 1 kwh=860 now campare this with your turbine kcal for 1kwh now you came to know how much is your turbine efficiency................................................................................
What is the effect of steam turbine control valve throttling in turbine efficiency?
In Boiler follow turbine mode , Boiler produces a constant pressure behind throttling valve and throttling valve adjusts necessary pressure and required steam as High Pressure steam for entering the turbine . In Valves Wide Open (VWO) mode the efficiency is maximum and we haven't any loss. (It's nearly 106% Turbine MCR) . In Turbine MCR , we have a little loss and consequently a little bit worse heat rate . In partial load , loss is more and efficiency worse.
What is reheat factor in power plant?
The reheat factor in the steam turbine refers to the Thermodynamic effect on the turbine efficiency. Others factors includes the cumulative heat, and the steam turbine condition curve.
What is the effect or reheater in the gas turbine?
1.Turbine output is increased for same compressor work. 2.As more heat is supplied,thermal efficiency decreases.
A steam turbine has an efficiency of 40 percent A steam engine has an efficiency of 25.0 percent Suppose both devices are provided with 1000J of thermal energy How much more useful work will the ste?
The steam turbine will produce 400 J of output, and the steam engine 250 J. That's what the efficiency figure means.
What is the efficiency of thermal power plant?
A modern combined cycle gas turbine/ steam turbine power plant can reach almost 60% efficiency.

How inefficiencies of compressor and turbine affect back work ratio and efficiency of gas turbine?
Inefficiencies in the compressor of a gas turbine cycle increase the back-work ratio and decrease the thermal efficiency of the gas turbine cycle, since they increase the compressor work.
What is the efficiency of pelton wheel turbine used in the lab?
0 to5 %
What is the effect of steam turbine control valve throttling in turbine efficiency?

How do you increase a Thermal efficiency of brayton cycle?
by increasing the turbine inlet gas temperature
What are the effects of humidity on gas turbine performance?
an increase in relative humidity will increase the Gas turbine output. and thermal efficiency. when the ambient tempeature is high at that time also if RH is high it will have a slight positive impact on GT output & Efficiency.
Is it possible to attach a wind turbine to an airplane to increase efficiency?
No. The amount of energy gained will be less than spent by the aircraft to overcome the drag created by your turbine.
What is the effect or reheater in the gas turbine?
1.Turbine output is increased for same compressor work. 2.As more heat is supplied,thermal efficiency decreases.
Why is it advantageous to use steam as hot as possible in a steam driven turbine?
in practice;the steam MUST be in the superheated region before entering the turbine.superheated steam means there is not moister in the steam (dry steam)the reason is moister will damage the turbine blades.in theory;the hotter the temperature the better the efficiency (look up vapor power cycles)work done by the turbine = the enthalpy (at temp. of steam entering the turbine)- the enthalpy at the turbine exist.the efficiency = work done by the turbine / the heat input.
Do you use HHV or LHV for gas turbine efficiency calculation?
Gas turbine manufacturers generally state the efficiency of their turbines using LHV. However, natural gas in the U.S. is bought and sold on an HHV basis, so be careful that you don't mix units. Otherwise, you will buy a gas turbine that is too small for your anticipated needs.
