3.) Product with Cp = 0.75 Btu/lb°F is flowing at a rate of 3300 lb/h and has to be cooled from 221°F to 160°F. ? Cooling water at 60°F at a mass flow rate of 10,000 lb/h is used. ? The overall U of the heat exchanger is 115 Btu/h ft2 °F. Calculate the outlet water temperature (will be the same for both) ____________________ and the heat exchanger area for: A co-current flow shell-and-tube heat exchanger. ____________________ A counter-current flow shell-and-tube heat exchanger. __________________
