Water flows through a vertical pipe of diameter 20 cm. Flow is measured by a venturi meter having a throat diameter of 10 cm. The elevation difference between the throat and inlet of the pipe is 30 cm. Mercury is used as a manometric fluid. Calculate (A) The flow rate (in l/s) for deflection of 10mm in the manometer column. (B) The manometric deflection (in mm) for the flow rate of 50 l/s.
