Unformatted text preview: cycle operating at a pressure of 7.5 kPa. It then passes through a pump that raises its pressure to 5 MPa which is followed by an open feedwater heater. Steam at 5 MPa and 300 ° C also enters the open feedwater heater. Determine a. Pump power required b. Mass flow rate of steam into the open feedwater heater. c. Pump power required for a pump isentropic efficiency of 63% ME 201 Thermodynamics 2 Hint for Problem 1 You may wish to include the total volume as a column on your property table. That is, Node T(K) P(kPa) v(m 3 /kg) V(m 3 ) u(kJ/kg) φ (kJ/kg K) Figure for Problem 2 Pump Condenser Feedwater Heater Steam Input...
