3.) The steam power plant requires 100 gallons per minute to cool the steam in the condenser from an exhaust pressure of 100 kPa. The feedwater pressure is 100 bar and 500 degrees Celsius. The condensate leaves the condenser at saturated liquid. The cooling tower temperature for the leaving cooling water is 25 degrees Celsius and the cooling water leaving the condenser is 42 degrees Celsius. Calculate the mass of the steam in kg/s assuming ideal rankine cycle and standard density of cooling water.
