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, and the orifice drains to the atmosphere. Neglecting the effect of the kinetic energy correction factor, calculate (a) the initial velocity from the tank and (b) the time required to empty the tank. Does the loss coefficient of the orifice cause a significant increase in the draining time of the tank?

Question

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,
and the orifice drains to the atmosphere. Neglecting the
effect of the kinetic energy correction factor, calculate (a)
the initial velocity from the tank and (b) the time required
to empty the tank. Does the loss coefficient of the orifice
cause a significant increase in the draining time of
the tank?
