The system consists of a plate type heat exchanger, where hot water from a geyser serves as the hot fluid and a separate cold fluid flows through the system. The input and outlet connectors are arranged to form a counterflow heat exchanger, facilitating efficient heat transfer between the fluids. By measuring the relevant parameters during the flow of hot and cold fluids through the alternating plates, students can calculate the heat transfer rate, Log Mean Temperature Difference (LMTD), heat transfer coefficients, and the overall efficiency of the heat exchanger.

Experimental Objective 

The Plate Heat exchanger is a 4plate brazed model that demonstrates the basic principles of heat transfer

To determine the overall heat transfer coefficient in a plate type heat exchanger at different hot fluid flow rate
