Challenge Problems
Push your limits with challenges.
Question 1
Design a heat exchanger for an industrial process requiring an outlet temperature of 85°C from a hot fluid entering at 100°C, with a cold fluid at 30°C needing to exit at 50°C. Calculate LMTD, and estimate the heat transfer rate if the area is 25 m² with an overall coefficient of 150 W/m²K.
💡 Hint: Ensure calculations for LMTD consider both temperature differentials.
Question 2
A refrigeration system aims to maximize heat transfer efficiency. If the system can achieve a maximum heat transfer of 120000 W, yet only 90000 W is effectively transferred, determine effectiveness and the implications for further design improvements.
💡 Hint: What challenges could slow down ideal efficiency?
