As a air-conditioning commissioning technician we would plot on the pump curve the impeller diameter from the no flow readings (shut off head), also plot the circulating pressures to work out the actual flows off the curves at both flows points to back up the annubar readings (measured actual flow).
Also from the volts and amps we can work out the pump kW and efficiency.
From there the system can be balanced if it was a chilled or heating hot water circuit at design flow. Thanks for the video!

I understand that pressure will vary by institution, but it would have been nice to see what all those readings were and how they changed throughout the test.

Nice Video, It would have been nice to have OSY instead of B-Fly valves to open and close. I've seen water turbulence destroy the neoprene on the inside of the valve. In addition have a better CLA casing relief valve that you can visually see water discharge at churn discharge into a pump room floor drain

Sir at zero flow what valves shall be closed? Usually relief valve and flow meter is at the same pipe return to tank.

What was the setup? Closed loop? Pump discharge to pump suction? Or from the supply tank back to the supply tank?  With a tank supply & return setup would a pitot test setup every 3 years be used?  Or is that only applicable to a diesel fire pump?  What about the 6 auto test starts?  Good info, thanks.

What is the mark  of this pump ?

I know these guys!

What about 50% after churn? I guess we do things alittle different in Pittsburgh.

What's the equipment you've used in getting the rpm?

Nicest pump room ever. Is this school for you guys?
