An organic liquid is heated from 20°C to 40°C by hot water in a 1:1 pass shell-and- tube heat exchanger in counter-current flow. The inlet temperature of the water stream is 85oC and flows in the shell side. The organic liquid flows through a bundle of 200 tubes of outside diameter 21 mm with a wall thickness of 2 mm. The flows of the organic liquid and water are 40 kg s and 15 kg s1, respectively (a) Calculate the...

Hot and cold water streams exchange heat in a double pipe heat exchanger in counter current flow. The pipes are 3 ft long. The inside pipe is a 5/8 inch BWG 12 copper tube. The outside pipe is a 1 inch Sch 40 steel pipe. The outside pipe is insulated to minimize heat loss to the surroundings. The hot water enters the inside tube at 180F with a flow rate such that Re = 10000 The cold water flows through...
