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.
Why temp drops during throttling?
Throttling is the process of passing gas through a narrow opening at a high velocity. While doing so the gas expands thereby providing a cooling effect.
What is effect on turbine generator if frequency is high or low?
turbine will trip
How many watts does an eighty foot tall wind turbine produce?
The height of a wind turbine has no impact on the turbine's output wattage. The factors that effect the watts produced are: * The efficiency of turbine design (this is at most 59%) * the density of the air * the radius of the turbine (that is, the length of each fin) * the velocity of the wind passing through the turbine An 80 ft tall turbine would presumably have a fin length (that is, turbine radius) of at most 30 ft. Thus, at sea level on a 59 degree (F) day, in an 8 m/s (18mi/h) wind, with the most efficient turbine design possible, you would generate approximately 15.4 Kilowatts.
