Section C – shell and tube heat exchanger sizing The vapour condenser for the combined gas-steam power cycle described in Section B heats river water from 15 °C to 18 °C. The condenser is a shell and tube heat exchanger with one shell pass and two tube passes. The cooling water is inside the tubes while the shell side has the condensing vapour. More details: a. The tube OD is 1 ¼” (inches), the tube wall thickness is 0.05 inches....

Problem 3 (20 points) A cross-flow heat exchanger consists of a bundle of 32 tubes in a long duct. Hot water at 150°C and a mean velocity of 0.5 m/s enters the tubes having inner and outer diameters of 10.2mm and 12.5mm and has to be cooled to 136°C. The tubes are made of steel of thermal conductivity k-40 W/m.K. Air at 10°c enters the exchanger (unfinned) with a volumetric flow rate of 1.0 m3/s. The convective heat transfer coefficient...

The condenser of a large steam power plant is a heat exchanger in which steam is condensed to liquid water. Assume the condenser to be a shell-and-tube heat exchanger consisting of a single shell and 30,000 tubes, each executing two passes (see figure below). The tubes are of thin wall construction with D=25mm, and steam condenses on their outer surface with an associated convection coefficient ho=11,000W/ m K The heat transfer rate that must be effected by the heat exchanger...

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...
