.... It had two openings—one at the bottom for coolant inlet and the other at the top for coolant outlet. The working fluid passed through a copper tube 10 mm i.d. 12 mm o.d. and 18 m long, made into two coaxial coils having 0.31 m and 0.25 m pitch circle diameters. To augment the heat transfer coefficient...
