To ensure rapid flow, heat is put into the pipe at the rate of 100,000 Btu/hr. What is the entalpy change in the oil per pound? Oil of average Cp= 0.8 Btu/(lb)(F) flows from an open reservoir standing on a hill 1000ft high into another open reservoir at the bottom. Assume that a 1-hp pump (50% efficient) is added to the pipeline to assist in moving the oil. Determine the enthalpy change per pound of the oil now?
