Question: Problem 3. A rectangular swimming pool has a volume of (V) of 1000m3 and water depth (h) of 3m. The water in the swimming pool

Problem 3. A rectangular swimming pool has a volume of (V) of 1000m3 and water depth (h) of 3m. The water in the swimming pool is evaporated to atmosphere at 25C. The air moisture is 30% of its saturated value and saturated vapor pressure of water (PA) is 0.032atm and Henry's constant is 2105Lw/Ls. Assuming 1kg water is evaporated from the pool daily at constant temperature (25C) and humidity is (30%) a) Calculate two-film water and air phase mass transfer coefficients ( KA2 and KA1) as cm/h. (10p) b) Calculate the time required as days to decrease the water depth from 3m to 2m. (10p) Not: The density of water is 1000kg/m
