A counterflow heat exchanger operates at steady state with negligible kinetic and potential energy effects. In one stream, liquid water enters at 17^∘ C and exits at 25^∘ C with a negligible change in pressure. In the other stream, Refrigerant 134a enters at 14 bar, 80^∘ C with a mass flow rate of 5 kg / min and exits as saturated liquid at 52^∘ C. Heat transfer from the outer surface of the heat exchanger can be ignored. Determine (a) the mass flow rate of the liquid water stream, in kg / min.

Oil in an engine is being cooled by air in a cross-flow heat exchanger, where both fluids are unmixed. Oil cp.h = 2047 J/kgK flowing with a flow rate of 0.026 kg/s enters the heat exchanger at 75C, while air cp.c = 1007 J/kgK enters at 30C with a flow rate of 0.21 kg/s. The overall heat transfer coefficient of the heat exchanger is 53 W/mK and the total surface area is 1 m. Determine the heat transfer effectiveness and the outlet temperature of the oil.

A double-pipe parallel-flow heat exchanger is to heat water ( Cp=4180 J / kg · ^∘ C ) from 25^∘ C to 60^∘ C at a rate of 0.2 kg / s. The heating is to be accomplished by geothermal water ( Cp=4310 J / kg · ^∘ C ) available at 140^∘ C at a mass flow rate of 0.3 kg / s. The inner tube is thin-walled and has a diameter of 0.8 cm . If the overall heat transfer coefficient of the heat exchanger is 550 W / m^2 · ^∘ C, determine the length of the heat exchanger required to achieve the desired heati

Ammonia enters a counterflow heat exchanger at -20^∘ C, with a quality of 35 %, and leaves as saturated vapor at -20^∘ C. Air at 300 K, 1 atm enters the heat exchanger in a separate stream with a flow rate of 4 kg / s and exits at 285 K, 0.98 atm. The heat exchanger is at steady state, and there is no appreciable heat transfer from its outer surface. Neglecting kinetic and potential energy effects, determine the mass flow rate of the ammonia, in kg / s, and the rate of entropy production with
