Twenty degree C air enters a tube bank which is to be used to remove 150 [kW] of heat from condensing refrigerant. The refrigerant is flowing inside the tubes of the bank and causes the external tube surfaces to be maintained at 100o C. The air is accelerated by a fan to 8 [m/s] upstream of the bank. The bank is to be constructed of transverse rows of fifty 8 [mm] O. D. tubes 0.75 [m] wide with the center-to-center transverse spacing equal to 15 [mm].
