... coils having 0.31 m and 0.25 m pitch circle diameters. To augment the heat transfer coefficient between the coolant and the outer surface of the duct, the velocity of the coolant past the tube coils was increased by putting a closed empty cylinder drum (30 cm long and 22 cm diameter) coaxially. Thus...
