Q1: The discharge through a 100 mm diameter external mouth piece fitted to the side of a large vessel is 0.05948 m3/s. The head over the mouth piece is

A 2 m

B 2.5 m

C 3.0 m

D 4.0 m

ANS:D - 4.0 m

This loss of head, sometimes, reduces the coefficient of discharge by a small amount (up to 0.82). But, for all practical purposes, the value of coefficient of discharge is taken as 0.855.
