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.

Question
Transcribed Image Text:3). A 2.4-m-diameter tank is initially filled with water 4 m above the centre 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?
