) A circular swimming pool has a diameter of 16 m. The circular side of the pool is 4 m high, and the depth of the water is 3.5 m. (The acceleration due to gravity is 9.8 m/s2 and the density of water is 1000 kg/m3.) How much work (in Joules) is required to: (a) pump all of the water over the side

Use henry's law and the solubilities given below to calculate the total volume of nitrogen and oxygen gas that should bubble out of 1.7 l of water upon warming from 25 Ëšc to 50 Ëšc. assume that the water is initially saturated with nitrogen and oxygen gas at 25 Ëšc and a total pressure of 1.0 atm. assume that the gas bubbles out at a temperature of 50 Ëšc. the solubility of oxygen gas at 50 Ëšc is 27.8 mg/l at an oxygen pressure of 1.00 atm. the solubility of nitrogen gas at 50 Ëšc is 14.6 mg/l at a nitrogen pressure of 1.00 atm. assume that the air above the water contains an oxygen partial pressure of 0.21 atm and a nitrogen partial pressure of 0.78 atm.
