The apparatus consists of a concentric tube heat exchanger packed with glass/metal packings. Hot water flows through outer tube and cold air flows in inner tube. Flow rates of hot and cold fluid are measured using Rotameters. A magnetic drive pump is used to circulate the hot water from a re-cycled type water tank, which is fitted with heaters and Digital Temperature Controller.
