3.) Product with Cp = 0.75 Btu/lb°F is flowing at a rate of 3300lb/h and has to be cooled from 221°F to 160°F. ? Cooling water at60°F at a mass flow rate of 10,000 lb/h is used. ? The overall U ofthe heat exchanger is 115 Btu/h ft2 °F. Calculate the outlet watertemperature (will be the same for both) ____________________ andthe heat exchanger area for: A co-current flow shell-and-tube heatexchanger. ____________________ A counter-current flowshell-and-tube heat exchanger. __________________
