2. Petrol from a tank passes through a vertical Venturi meter having an inlet diameter of 150mm and throat diameter of 37.5mm. The inlet is 380mm above the throat. Pressure gauges are fitted at inlet and throat. Assuming that energy degradation between inlet and throat may be expressed as 35u²/2g, u being the flow velocity at inlet. The pressure difference between inlet and throat is found to be 31 KN/m². (a) Find the coefficient of discharge. Assume that the specific gravity of petrol is 0.78 (b) Find the flow rate through the meter in m³/s.

2. Petrol from a tank passes through a vertical Venturi
meter having an inlet diameter of 150mm and throat
diameter of 37.5mm. The inlet is 380mm above the throat.
Pressure gauges are fitted at inlet and throat. Assuming
that energy degradation between inlet and throat may be
expressed as 35u²/2g, u being the flow velocity at inlet.
The pressure difference between inlet and throat is found
to be 31 KN/m².
(a) Find the coefficient of discharge. Assume that the
specific gravity of petrol is 0.78
(b) Find the flow rate through the meter in m³/s.
