A conical flask contains water to height H = 36.8 mm, where the flask diameter is D = 29.4 mm. Water drains out through a smoothly rounded hole of diameter d = 7.35 mm at the apex of the cone. The flow speed at the exit is approximately V = (2gy)]^1/2, where y is the height of the liquid free surface above the hole. A stream of water flows into the top of the flask at constant volume flow rate, Q = 3.75 X 10^-7 m^3/hr. Find the volume flow rate from the bottom of the flask. Evaluate the direction and rate of change of water surface level in the flask at this instant.
