Unformatted text preview: Calculate the area required for this exchanger, assuming that the overall heat-transfer coefficient remains at 320 W/m 2 ºC. 3. Water at a rate of 45500 kg/hr is heated from 80ºC to 150ºC in a shell-and-tube heat exchanger having two shell passes and eight tube passes with a total outside heat transfer surface area of 925 m 2 . Hot exchaust gases having approximately the same thermophysical properties as air enter at 350ºC and exit at 175ºC. Determine the overall heat transfer coefficient based on the outside surface area....
