Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A heat exchanger has \(\Delta T_1 = 80°C\) and \(\Delta T_2 = 40°C\). Calculate the LMTD and then evaluate the heat transfer rate if U = 250 W/m²K and A = 50 m².

💡 Hint: Use the LMTD formula to find the average temperature difference before applying it to the heat transfer rate equation.

Challenge 2 Hard

Consider a heat exchanger with a correction factor F of 1.2. If the calculated heat transfer rate without F is 100 kW, what is the adjusted heat transfer rate?

💡 Hint: Remember that the correction factor increases the heat transfer rate.
