A Venturimeter with an entrance diameter  of 0.3 m and a throat diameter  of 0.2 m is used to measure the volume of gas flowing through a pipe .  The height difference between the centre of the throat and that at the entrance is 20mm, and the discharge coefficient of the meter is 0.96. Assuming the density of the gas to be constant at 2kg/m³ and ignoring all frictional  losses, calculate  the volumetric flow rate when the pressure difference, P1-P2, between the entrance and the throat is measured as 0.06 m on a water U-tube nanometer.

A Venturimeter with an entrance diameter  of 0.3 m and a throat diameter  of 0.2 m is used to measure the volume of gas flowing through a pipe . 

The height difference between the centre of the throat and that at the entrance is 20mm, and the discharge coefficient of the meter is 0.96. Assuming the density of the gas to be constant at 2kg/m³ and ignoring all frictional  losses, calculate  the volumetric flow rate when the pressure difference, P1-P2, between the entrance and the throat is measured as 0.06 m on a water U-tube nanometer.
