A swimming pool has a leak . The pool is a rectangle measuring 32 ft long, 16 ft wide and on average 7 ft deep. Every other day, 6 inches of water is added to the pool. a) Using the mass balance approach, what is the leakage rate (m3/day) from the pool. Assume that inch of water evaporates per day. b) if I am going away for 12 days and can't add water to the pool but needs to be sure that the water level stays above the skimmer drain (a drain line that pulls water to the pump) otherwise air will get into the pump and damage it. The skimmer is 16 inches below the normal water level (7 ft). How many cm must be filled above the normal depth to ensure that air does not get into the pump?
