This question is regarding the transportation, for the flow of water to the heat exchanger (HEX-100). The water from the reservoir underground flows through a straight horizontal pipe (at ground level) to a pump, and subsequently to the heat exchanger. Surface H20 130 120 PA = P1 HEX-110 Saturated vapour NH3 T = 20 C -Wp Wr NH3 Cycle T-100 P-100 Saturated liquid NH3 T3 = 10 C P2 = P3 100 110 Underground H20 HEX-100 Refer to the water pipe design specifications below: = = Pipe length = 650 m, pipe internal diameter = 0.6 m, Ah; = 19.8 m, Pa = 1 bar and P2 = 1.5 bar Compare and evaluate the different correlations which can be applied to obtain the frictional pressure drop in a pipe. Which correlation is applicable for the flow of cold water? Justify your answer fully.
