(b): A horizontal pipe 50 mm in diameter is fitted with a venturi tube which has a throat diameter of 40 mm. The pipe carries water (Density 1000kg/m³) at a pressure of 30 kPa (gauge) and velocity 3 m/s upstream of the throat (position 1). Assuming there are no frictional losses in the flow, determine: ?. the Mass flow rate in kg/s. ii. the Velocity at the throat (position 2) in m/s iii. the Pressure at the throat (position 2) in kPa. iv. the Pressure Head at the throat (position 2) in m the Velocity Head at the throat (position 2) in m V. vi. the Total Head, given that h? = h? = 2.0m (Should be the same at positions 1 and 2). ventun tube direction of flow throat
