Cold water with an enthalpy of 8 Btu / lbm enters a heater at the rate of 5 lbm / sec with a velocity of 10 ft / sec and at a potential of 10 ft with respect to the other connections shown in Figure P2.14. Steam enters at the rate of 1 lbm / sec with a velocity of 50 ft / sec and an enthalpy of 1350 Btu / lbm. These two streams mix in the heater, and hot water emerges with an enthalpy of 168 Btu / lbm and a velocity of 12 ft / sec. (a) Determine the heat lost from the apparatus. (b) What percent
