Question

derive an expression for rate of flow fluid mesured as mesured by venturimeter​

Answer 1

Explanation:

Venturi meter : This device is used to measure velocities and mass rate of flow of liquid at the different cross-sections of a pipe. It consists of a constriction inserted in a pipe line and have tapers at the inlet and outlet, so that turbulence is avoided. See fig. Let at the cross-sectional areas A1 and A2, the velocities are υ1 and υ2 respectively. From the equation of continuity, A1υ1– = A2υ2

Answer 2

Ans= Derive an expression for the rate of flow of liquid through it. Venturimeter is based on Bernoulli's theorem. It consists of a two truncated tubes connected by a pipe at narrow ends. The pipe connecting the two tubes is called throat as shown in figure.
