To determine coefficient of Rotameter

Aim: To find out the coefficient of given Rotameter.

Requirements: Hydraulic bench and Rota Meter Apparatus.


 Rotameter is variable area flowmeter used to measure fluid flow. It works on the principle of upthrust force exerted by fluid and force of gravity. The buoyant force exerted on an immersed object is equal to the weight of liquid displaced by the object.

Procedure and Sample Calculation Shown below.

For Calculation You can use RotaMeter Coefficient Calculator.
