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...

6 Problem 4 (25%) A 2-shell passes and 4-tube passes heat exchanger is used to heat glycerin (Cp.gly = 2447) entering at 15 °C by hot water (Cp water = 4180 f.), which enters at 90°C. The thin-walled inner tube has a 4 cm diameter and a total length of 15 m. The hot water flows through the tube at a total rate of 0.265 kg/s, and the glycerin through the shell at a rate of 0.6 kg/s. The convection...

A counter-flow heat exchanger is stated to have an overall heat transfer coefficient of 284 W/m2.K when operating at design and clean conditions. Hot fluid enters the tube side at 101°C and exits at 71°C, while cold fluid enters the shell side at 27°C and exits at 42°C. After a period of use, built-up scale in the heat exchanger gives a fouling factor of 0.0004 m2 K/W. The surface area is 93 m². Assume both hot and cold fluids have...

Problem 3 (60 Points). A 1-2 shell-and-tube heat exchanger must be designed to heat 2.5 kg/s of water from 15 to 85°C. The heating is to be accomplished by passing hot engine oil at a rate of 5.2 kg/s, which is available at 160°C, through the shell side of the exchanger. The oil is known to provide an average convection coefficient of 400 W/m2K on the outside of the tubes. Ten tubes passes the water through the shell....

6. A shell-and-tube heat exchanger with 2-shell passes and 12-tube passes is used to heat water (c 4,180 J/kg K) flowing at a rate of 4.5 kg/s in the tubes from 20°C to 70°C. Heat is supplied by hot oil (cp 2300 J/kg K) that enters the shell side at 170°C at a rate of 10 kg/s. If overall heat transfer coefficient on the tube-side is 350 W/m-K, determine the heat transfer surface area on the tube side.
