Challenge Problems
Push your limits with challenges.
Question 1
A heat exchanger needs to transfer 500 kW of heat. If you know the inlet temperature is 120°C and outlet is 80°C on the hot side, but the outlet temperature on the cold side is unknown. Using the Effectiveness-NTU method, determine the outlet temperature if the cold side inlet is at 25°C.
💡 Hint: You’ll need to calculate Qmax first based on the minimum capacity.
Question 2
Design a shell and tube heat exchanger for a chemical plant operation where the pressure drop must not exceed 10 kPa. Discuss the considerations involved in balancing thermal efficiency and pressure drop.
💡 Hint: Review the relationship between flow velocity, area, and pressure drop.
