Question

A circular water tank of 2 m2\text{ m} diameter has a circular orifice of diameter 0.1 m0.1\text{ m} at the bottom. Water enters the tank steadily at a flow rate of 20 litre/s20\text{ litre/s} and escapes through the orifice. The coefficient of discharge of the orifice is 0.80.8. Consider the acceleration due to gravity as 9.81 m/s29.81\text{ m/s}^2 and neglect frictional losses. The height of the water level (in m, round off to two decimal places) in the tank at the steady state, is ___________.
