If you mean energy (which is what you sell), read How much energy could I generate from a hydro turbine?. If you mean power, read on.. Power is the rate of producing energy. Power is measured in Watts (W) or kiloWatts (kW). Energy is what is used to do work and is measured in kilowatthours (kWh) or megawatthours (MWh).
Mar 17, 2015· Using the outlet specific enthalpy, calculate the outlet properties: Step 4: Calculate Steam Turbine Energy Out and Generation (Power Out) Energy Out = (Inlet Specific Enthalpy Outlet Specific Enthalpy) * Mass Flow; Power Out = Energy Out * Generator Efficiency; Assumptions. Inlet Mass Flows equal Outlet Mass Flow.
Mill power as measured in many plants is motor input power, that is, electrical energy going into the motor. It has to be converted to power at the mill pinionshaft. This is done by applying the motor efficiency factor (electrical and mechanical losses) to obtain motor output power.
Example Wind Power. The actual available power from a wind mill with diameter 1 m, efficiency (20%) with wind velocity 10 m/s can be calculated as. P a = () ( kg/m 3) π (1 m) 2 (10 m/s) 3 / 8 = W.

Calculation of Wind power and energy Principle. A windturbine is composed of rotor often fitted with several blades. The rotor is fixed at a nacelle installed on the top of a vertical mast. A central rotating shaft connects the major components of the drivetrain.
Betz''s law indicates the maximum power that can be extracted from the wind, independent of the design of a wind turbine in open flow. It was published in 1919 by the German physicist Albert Betz. The law is derived from the principles of conservation of mass and momentum of the air stream flowing through an idealized "actuator disk" that extracts energy from the wind stream.
Power Coefficient It''s an Efficiency. I would like to call it (and some people do) overall turbine system efficiency. The wind power industry often calls it the Power Coefficient, and gives it the symbol Cp.. The technical and product literature is now full of it (the term Cp I mean), so Power Coefficient it shall be for the rest of this page.
What is the efficiency of different types of power plants? Heat rate is one measure of the efficiency of electrical generators/power plants that convert a fuel into heat and into electricity. The heat rate is the amount of energy used by an electrical generator/power .
Turbine Steam Consumption Calculations. ... The isentropic efficiency η at load P can be estimated by. η = m·P / (P R + m·P) where P R is the rated turbine power. The specific enthalpy at the turbine exhaust conditions is then. h LP = h HP η·(h HP h LPisen) The steam consumption at .
Define the steam turbine calculation. In this example, a power generator in a sugar mill is driven by a steam turbine that receives 52,462 pounds per hour of superheated steam at 450 pounds per square inch absolute (psia) pressure with a temperature of degrees Fahrenheit.
Example: an offshore wind turbine with a radius of 80 meters at a wind speed of 15 meters per second has a power of megawatts, if air density and efficiency factor have the given values. The most important factor for a high power is the wind speed, which goes into the calculation at the power .

However, hydro power turbine generators are very efficient when compared to wind turbine generators and solar panels. Efficiencies of around 70% can be expected which is to say that 70% of the hydraulic energy of the flowing water can be turned into mechanical energy spinning the turbine generator. The remaining 30% is lost.
The results show that as the power turbine inlet temperature reduced from to, the power turbine efficiency increased from % to % and the power .
Electric Power Efficiency Power efficiency. Power efficiency is defined as the ratio of the output power divided by the input power: η = ⋅ P out / P in. η is the efficiency in percent (%). P in is the input power consumption in watts (W).. P out is the output power or actual work in watts (W).. Example
