engineering recuitment HPCL Junior Executive 2025 Mock Test Fluid Mechanics Flow Measurement Venturimeter
A venturi meter of 20 mm throat diameter is used to measure the velocity of water in a horizontal pipe of 40 mm diameter. If the pressure difference between the inlet and the throat is found to be 30 kPa, then neglecting frictional losses, the flow velocity is
1
0.2 m/s
2
1 m/s
3
1.4 m/s
4
2.0 m/s
