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.

What is effect if inlet temperature is increased on gas turbine?
Increasing the inlet temperature of a gas turbine can improve its efficiency and power output. This is because higher temperatures lead to better energy conversion and expansion of the gas, resulting in more work output from the turbine. However, there is a limit to how much the temperature can be increased before it affects the materials and components of the turbine, potentially reducing its reliability and lifespan.
What are the effect of temperature fluctuation on gas turbine?
If you are referring to a gas engine then the temperature affects the efficiency of the engine. The colder it is, the less efficient. The hotter it is the more efficient. I hope that this answers your question
What will be the effect to the thermal efficiency to a simple Rankine cycle when the turbine work output decrease?
The efficiency will decrease.Remeber the formula for effiency for a cycle:What we want over what we pay for. So,ηT=WT/QAWhereWT = Work done by the turbineQA = Heat taken from the hot reservoir

What does efficiency do on a pick-axe?
It doesn't 'do' anything. Efficiency measures the effect something has in proportion to the energy required for that effect.
What is the effect on a steam turbine if the system is running in under frequency?
It results in reduced ventilation and affect the turbine more than the generator.
What are some words that begin with Ef?
effect...efficiency
