Water is discharging through a circular orifice plate 25mm in diameter in the vertical side of the tank of a constant plan area 0.4m2. It is observed that the time taken for the water level to fall from 1.5m to 1.4m above the orifice is24.5 seconds. Show that the average volumetric flow rate is 1.633*10^-3 m^3/s.By approximating the height as being a constant value (1.4m, 1.5m or 1.45m) for discharge rate calculation, estimate the coefficient of discharge for this orifice plate, and give highest and lowest plausible values from the data supplied.

Question
Water is discharging through a circular orifice plate 25mm in diameter in the vertical side of the tank of a constant plan area 0.4m2. It is observed that the time taken for the water level to fall from 1.5m to 1.4m above the orifice is
24.5 seconds. Show that the average volumetric flow rate is 1.633*10^-3 m^3/s.
By approximating the height as being a constant value (1.4m, 1.5m or 1.45m) for discharge rate calculation, estimate the coefficient of discharge for this orifice plate, and give highest and lowest plausible values from the data supplied.
