Question: A certain industrial process requires a steady stream of saturated vapor water at 200 kPa at a rate of 2 kg/s. There are two alternatives

A certain industrial process requires a steady stream of saturated vapor water at 200 kPa at a rate of 2 kg/s. There are two alternatives for supplying this steam from ambient liquid water at 20C, 100 kPa. Assume pump efficiency of 80%.
a. Pump the water to 200 kPa and feed it to a steam generator (heater).
b. Pump the water to 5 MPa, feed it to a steam generator and heat to 450C, then expand it through a turbine from which the steam exhausts at the desired state.
