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...

2.- Hot oil (Cp = 2200 J/kg °C) is to be cooled by water (Cp = 4180 J/kg °C) in a 2-shell-passes and 12-tube-passes heat exchanger. The tubes are thin-walled and are made of copper with a diameter of 1.8 cm. The length of each tube pass in the heat exchanger is 3 m. Water flows through the tubes at a total rate of 0.1 kg/s, and the oil through the shell at a rate of 0.2 kg/s. The water...

QUESTION 4 (25 marks) Water (Cr 4.208 kJ/kg.K) at flow rate of 5.11 kg/s s heated from 78°C to 98°C in an economizer inside a boiler. The boiler is a cross flow heat exchanger with single pass, shell fluid mixed and other fluid unmixed. The average water velocity in the 1.5 cm diameter (D) tube is 1.27 m/s. On the shell side, hot air (C,-1.0341 kJ/kgK) was used as the heating fluid with 7.3 kg/s of it entering the exchanger...
