Water flows at the rate of 40ml/sec through an opening at the bottom of a large tank in which the water is 5.0 meter deep. the initial pressure on the surface of the water is atmosphere pressure. calculate the flow rate out of the tank at the opening if an additional pressure of 50kPa is applied to the top of the water tank. apply Bernoulli's equation (twice) in solving this problem, once before, and once after the additional pressure is added to the surface. assume (due to the large volume of the tank) that the water velocity at the surface is essentially zero in both cases. flow rate should be expressed in units of m^3/sec
