Question

Maximum pressure recovery is offered by _________________ amongst below constant area variable head flow meters.

• A. orifice plate
• B. pitot tube
• C. venturimeter
• D. flow nozzle

Answer 1

Answer:

C. venturimeter

A venturimeter is a device used to measure the flow rate of a fluid by constricting the flow passage and measuring the resulting pressure difference. The venturimeter has a higher coefficient of discharge than an orifice plate or a flow nozzle, which means that it has lower pressure losses and can recover more of the pressure energy of the fluid.
