Problem 8.24

Water is used to cool ethylene glycol in a 60-ft-long double pipe heat exchanger made of 4-std and 2-std (both type M) copper tubing. The water inlet temperature is 60°F and the ethylene glycol inlet temperature is 180°F. The flow rate of the ethylene glycol is 20 lbm/s, while that for the water is 30 lbm/s. Calculate the expected outlet temperature of the ethylene glycol and determine the pressure drop expected for both streams. Assume counterflow, and place the ethylene glycol in the inner tube. Compose a Summary of Performance chart.

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...

heat transfer problem A counterflow concentric tube heat exchanger is used to cool lubricant oil of a big gas turbine. The cooling water's flow rate through the interior aluminum tube (Di= 25mm) is 0.2kg/seg, while the oil's flow rate through the exterior ring (Do= 45mm) is 0.1kg/seg. The oil and the water enter at 100°C and 30°C respectively. How long does the tube have to be for oil to leave at 60°C? Oil at 80°C Cp = 2131 J/Kg K...
