Water enters a boiler with a flow rate of 1 kg/s at 100 kPa, 20oC and leaves as saturated vapor. Assuming no pressure loss and neglecting changes in ke and pe, determine
(a) The rate of heat transfer in kW.
(b) If the heating value of gasoline is 44 MJ/kg, what is the consumption rate of gasoline in kg/s? Use PC model for H2O. What-if Scenario: What would the fuel consumption rate if the water were preheated by solar radiation to 90oC?
