Water flows through a venturi meter whose diameter is 7 cm at the entrance part and 4 cm at the throat. The pressure is 380 kPa at the entrance and 150 kPa at the throat. Neglecting frictional effects determine the flow rate of water. You can take the density of water as 1000 kg/m, water viscosity as 0.001 kg/ms, atmospheric pressure as 101 kPa, and gravitational acceleration as 9.81 m/s.
