In Figure 1, the water at Point B has a mass flowrate of 8 lbm/s at a temperature of 90 F, the water at Point C has a temperature of 85 F and the water at Point A has a temperature of 70 F. Assume the properties of water are constant at 70 F. What is the mass flowrate at Point A in units of lbm/s? Select the answer that is closest to the true value. A) 0.667 B) 1.667 C) 2.67 D) 3.67 1 water L1 P L2 L3 oil out L6 HX L4 B 4 oil in A L5 C 2 water out
