Chapter 8, Problem 77P
A 2.4-m-diameter tank is initially filled with water 4 m above the center of a sharp-edged 10-cm-diameter orifice. The tank water surface is open to the atmosphere, amid the orifice drains to the atmosphere. Neglecting the effect of time kinetic energy correction factor, calculate (a) the initial velocity from the tank and (b) the time required to empty time tank. Does time loss coefficient of time orifice cause a significant increase in the draining time of the tank?

A 3-m-diameter tank is initially filled with water 2 m above the center of a sharp-edged 10-cm-diameter orifice. The tank water surface is open to the atmosphere, and the orifice drains to the atmosphere through a 100-m-long pipe. The friction coefficient of the pipe is taken to be 0.015 and the effect of the kinetic energy correction factor can be neglected. Determine (a) the initial velocity from the tank and (b) the time required to empty the tank.
