Power is measured in Watts (W) or kiloWatts (kW). Energy is what is used to do work and is measured in kilowatt-hours (kWh) or megawatt-hours (MWh). · In the example, if you had an efficiency rating of 60 percent, then you would divide that number by 100 to convert it to decimal format. Then multiply that number by the hydro power of 4,905 watts to calculate the water wheel's power of 2,943 watts.

Get MoreHeat rate is a term commonly used in power stations to indicate the power plant efficiency.The heat rate is the inverse of the efficiency: a lower heat rate is better. = The term efficiency is a dimensionless measure (sometimes quoted in percent), and strictly heat rate is dimensionless as well, but often written as energy per energy in relevant units. The efficiency of any turbine or engine can be defined as its ability to convert the input energy into useful output energy which is expressed in the form of the following equation.. Efficiency (ɳ) = Output / Input. An ideal turbine with efficiency is the one which converts all its input energy into output work without dissipating energy in the form of heat or any other form.
