Water is to be withdrawn from a S-m-high water reservoir by drilling a 1.5-cm-diameter hole at the bottom surface. Disregarding the effect of the kinetic energy correction factor, determine the flow rate of water through the hole if:

a. The entrance of the hole is well-rounded.
b. The entrance is sharp-edged.
