An ideal Rankine cycle has been analyzed and the data tabulated below: State T(oC) P (bar) q V (m3/kg) H (kJ/kg) S (kJ/kgK) 1 400 10 SH 0.307 3264.5 7.4669 2 179.88 0.5 0.981 3.177 2600.5 7.4669 3 81.32 0.5 0.0 0.00103 340.5 1.0912 4 -- 10 CL 0.00103 1.0912 The actual turbine based on this cycle is 92% efficient and the actual pump is 68% efficient. The cycle is designed for 8.5 kg/s of flow. What is the net power produced by this cycle (in kW)

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
