In Figure 1, the heat exchanger (HX) has a pressure drop of 25 psi on the water side. The heat exchanger inlet pipe velocity is 10 ft/s. Assume the properties of water are constant at 70 F. What is a loss coefficient "K" (based on the inlet pipe velocity) that can used to simulate this pressure drop in units of ft of water in the Darcy Weisbach head loss equation? Select the answer that is closest to the true value. A) 14.89 B) 22.3 C) 29.8 D) 37.2 --- OA OB OD 1 Figure 1 water L1 P L2 L3 oil out L6 HX L4 B 4 oil in A L5 C water out
