The maximum cooling water discharge temperature from the condenser at minimum water flow is most nearly:

A) 110F

B) 116 F

C) 125 F

D) 255 F

Example 38 Compressed ammonia vapor (252psia and 255F) is to be totally condensed (247psia and 110F). The liquid ammonia is maintained at a constant temperature of 110F. The ammonia flow rate is 17,250lbm/hr. Cooling tower water at 80F is to be used in a countercurrent flow arrangement. The maximum design return water temperature is 125F. The heat-release curve shown below applies. The following enthalpy data applies to the ammonia
