Electricity can be generated by boiling water to form steam, using a combustible energy source (such as coal or . Electricity can be generated by boiling water to form steam,

using a combustible energy source (such as coal or natural gas). Pumps pressurize the water drawn from a lake at 20.0 °C to a pressure of 11.71 bars, which enters the boiler. Steam leaves the boiler as saturated vapor at 11.71 bars with a flow rate of 500.0 kg/min. (Appx. A.6) A. At what rate must energy be input into the water in the boiler? (in megawatts) B. What percentage of the energy input is due to sensible energy (i.e., the energy to change temperature)? C. What percentage of the energy input is due to latent energy (i.e., the energy to change phase)?
