heat transfer
Test Yourself A Shell-and-tube heat exchanger, consisting of a single shell and 30.000 tubes, each executing two passes, is used in a large steam power plant to condense steam to liquid water. The steam condensed in the shell side of the heat exchanger with an associated convection coefficient (h) of 11.000 W/m2.°C. The heat transfer rate through the heat exchanger (O is 2x10' W. Cooling water is passing through a thin tubes with D = 2.5 cm, at...

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.

QUESTION 2 2. A shell and tube heat exchanger with two shell passes and four tube passes cools a chemical with a specific heat of 2385 J/kg K at a rate of 1.25 kg/s from 140°C to 80°C, using water at 35°C. The outlet temperature of the water is 85°C. Determine the area of heat exchanger if U= 800 W/m2-K. If the unit is operated with flow rates doubled, determine the heat transfer. Also determine the heat transfer if the...

A shell-and tube heat exchanger has one-shell pass and 2-tube passes. This heat exchanger is used to cool oil, flowing through the tube-side from 140°C to 50°C. The cooling is accomplished by water, flowing through the shell-side, which enters the heat exchanger at 15°C and leaves at 32°C. Each tube pass consists of 60, 2.54-cm-O.D. tubes with a wall thickness of 1.65 mm.if the inside and outside heat transfer coefficients are h1=260 W/(m^2°C) and h°=970 W/(m^2°C), respectively, and the fouling...
