Which of the following flow meters is based on the principle of fluid acceleration?
A. Turbine flow meter
B. Orifice plate
C. Magnetic flow meter
D. Ultrasonic flow meter
Answer:B
Which of the following flow meters is based on the principle of fluid acceleration?
A. Turbine flow meter B. Orifice plate C. Magnetic flow meter D. Ultrasonic flow meter
Explanation: Orifice plates use the principle of fluid acceleration to measure the flow rate of a fluid. They consist of a plate with a hole in it placed in the fluid flow. The pressure difference across the hole is proportional to the fluid flow rate.
