Chapter 7 – Condensers Problems
7.1 A 10 TR ammonia ice plant has a two-pass
shell-and-tube water-cooled condenser. The water enters at 30°C. The
temperature rise of water may be taken as 2.5°C. The refrigerant
condensing temperature is 35°C. The heat rejection ratio of the plant is
1.35. The condenser has 24 steel tubes of 21 mm OD and 13.65 mm ID.
Determine the length of the tubes.
