Part A f this energy is transferred by hot water passing through tubes in the water in an evaporative cooling tower, how much water must evaporate to cool the plant per second? kg/s At Submit My Answers Give up Part B How much water must evaporate to cool the plant per day? kg/day Submit My Answers Give up

Explanation / Answer

dQ = m*L

dQ/dt = dm/dt *L

dm/dt = P/L

dm/dt = 1000e6/(2.256e6) = 443.26 kg /s

part B)

dm/dt = 443.26*60*60*24 = 38297664 kg / day
