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 Btu/lb. The pump requires 3 Btu/s of power to operate. If kinetic energy effects are negligible and gravitational acceleration is 32.174 ft/s2, the heat transfer rate associated with this steady state process is most closely: A) 2.02 Btu/s from the liquid to the surroundings. B) 3.98 Btu/s from the surroundings to the liquid. C) 4.96 Btu/s from the surroundings to the liquid. D) 1.04 Btu/s from the liquid to the surroundings.
