Identify the incorrect statement concerning incompressible fluid flow through a Venturimeter.

Select your answer for: Identify the incorrect statement concerning incompressible fluid flow through a Venturimeter.
Show answer

Answer: C. Venturimeter occupies less space than an orificemeter

Explanation

Venturimeters feature a gradual converging section and a long diverging diffuser cone. This extended diffuser recovery cone requires significantly more physical installation length than an orifice plate. Therefore, claiming a venturimeter occupies less space than an orificemeter is completely incorrect. Orifice meters use flat plates inserted between flanges, making them extremely compact to install. Venturimeters minimize permanent pressure losses through smooth, streamlined convergence and divergence. Both meters operate on Bernoulli principles to measure fluid flow rates using pressure differentials.

Industrial piping designers choose orifice meters when physical installation space is severely restricted. Process plants select venturimeters for large water lines where minimizing pumping power loss is critical. Accurate flow measurement is essential for mass balance tracking in chemical manufacturing facilities. Option a states frictionless pressure is equal, which describes ideal Bernoulli behavior. Option b notes discharge depends on gauge difference, which is true for standard meter equations. Option d correctly notes venturimeters incur less power loss than orifice meters due to smooth recovery.
