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.

Air undergoes a constant pressure cooling process with no moisture added or removed. the air originally exists at 45 °c, 150 kpa and 35 % relative humidity. it is cooled until the temperature reaches 29 oc. determine (a) the relative humidity of the cooled air. (b) the dew point temperature of the cooled air in °c. (c) the heat removed during the cooling process in kj/kg. use the psychrometric chart to check your answers (this part will not be graded; however, it will you get comfortable using the psychrometric chart)
