Flow coefficient Cv value testing

[brightonk]

Hey, I am currently doing a project where I have to calculate/(predict) the cv values of a number of valves. at the moment I am calculating Reduced Bore ball valves where water will be going through them. I am now at the stage where I need to test the valves using some sort of flow loop system to validate my calculations. However I am stuck on what equipment/set up i will need in order to achieve this. I know I will need some sort of pressure measuring device, maybe a pitot tube?

Any sort of help will be appreciated

Thanks

!For testing the valves, you will need a flow loop system. This consists of a pump, pressure gauge, flow meter, and a control valve. You can then measure the pressure drop across the valve by varying the pump flow rate and measuring the pressure difference with the pressure gauge. You may also need a pitot tube if you want to measure the velocity of the fluid flow. Additionally, you may need a thermometer to measure the temperature of the fluid and ensure it is correct for your calculations.
