In this video tutorial, you will learn how to calculate the rate of heat transfer between hot and cold working fluids of a heat exchanger. You will also learn how to calculate the mass flow rate of the working fluid, in order to achieve the desired outlet temperatures from the heat exchanger.

Really good tutorial. This was explained very clear.
I have a question. If you have a pipe of certain length with running water. Only the last 2 meter is exposed to a fire that heats the water so that it exits the pipe with a temperature of 20⁰C higher than the inlet temperature. Pipe diameter is 22mm and flow rate is 0.06 litres/sec. How do you calculate energy since the water is flowing? Do you calculate in terms of time or in terms of volume?
Just a question: Suppose we have a hot plate and it's in contact with oil and another plate in a ratio of say 30:70 respectively (imagine a plate on a plate with oil grooves). How do we tackle heat transfer in this scenario?
