DESCRIPTION :- The apparatus consists of fabricated shell, inside which coil tubes on outer side are fitted. The present set up is a heat exchanger, with cold water flows through shell. Valves are provided to control the flow rates of hot and cold water. Flow rates of hot and cold water 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.
EXPERIMENTATION :- The main object of the experimental setup is to study the following at various flow rates: LMTD Heat transfer rate Overall Heat Transfer Co-efficient.
