question

Water cools the inside of a pipe, with the transfer of heat accomplished by the mechanism of forced convection. The mass flow rate is 200 lbm/hr. The pipe is 10 ft. long and has a 4 in. internal diameter. If the water has an entrance temperature of 40°F and an exit temperature of 100°F, what is the temperature of the inside wall surface?
