A parallel flow heat exchanger is used to transfer heat from hot water at 80oC, flowing at 5 L/min to cold water at 15oC which is flowing at a rate of 15 L/min. The overall heat transfer coefficient is 2000 W/m2oC and the area is 0.2m2.

Calculate the heat transfer rate, the outlet temperature of the cold water.

A thin-walled cross-flow heat exchanger is used to heat a petrochemical whose specific heat is 1800 J (kg K)-1 with hot water (Cp = 4180 J (kg K)-1). The petrochemical enters the heat exchanger at 20oC at a rate of 3.7 kg s-1, whilst the water stream enters at 110oC at a rate of 2.5 kg s-1. The heat transfer surface area of the heat exchanger is 4.8 m2 and the overall heat transfer coefficient is 940.30 W m-2K-1. Determine...

Hot water enters a counter-flow double-pipe heat exchanger at 180F with a velocity of 5 ft/s. Cold water at 80F flows at 3 ft/s in the outer section of the exchanger. The diameter of the inner pipe is 1 inch, the pipe wall thickness is 1/8", and the outer pipe diameter is 2 inches. The overall heat transfer coefficient times area per unit length UA/L = 150 Btu/hr-ft-F. If the exchanger is 16 feet long, what is the exit temperature...

Jack is operating a tubular, water-water heat exchanger when suddenly, the valve controlling the flow rate of the hot-water stream becomes stuck and he is now unable to adjust/control the flow rate of the hot-water stream. Additionally, the tube providing the hot water has become partially clogged, drastically reducing the flow rate of hot water entering the exchanger. How could you adjust the heat exchanger apparatus to maintain the same outlet temperature of the cold-water stream as before the incident?...

A hot fluid of specific heat 4100 J/kg K flows through a parallel flow heat exchanger at the rate of 3.5 kg/min with an inlet temp. of 105C. A cold fluid of specific heat 2350 J/kg K flows in at a rate of 9 kg/min and with inlet temperature 25C. Make calculations for maximum possible effectiveness if the fluid flow conforms to parallel flow arrangement.

Cold water enters a counter flow heat exchanger at 20ºC at a rate of 10 kg/s, where it is heated by a hot water stream that enters the heat exchanger at 80ºC at a rate of 2 kg/s. Assuming the specific heat of water to remain constant at Cp=4.18 kJ/(kg.ºC), determine the maximum heat transfer rate and the outlet temperatures of the cold and the hot water streams.
