static pressure measurement
(OP)
I need to find proper method to measure static pressure of 100% outside air water cooled air handler. I never did this and I do have a new manometer but don't quite know what I'm doing.





RE: static pressure measurement
The supply should yeild a positive value, and the return a negative value.
The tatal static pressure of the air handler will SP Outlet - (minus) the TP Inlet.
i.e Pressure SP Outlet 69 Pa
Pressure TP Inlet -272 Pa
Unit Static Pressure = 341 Pa
This can also be done at the fan to give the fan static pressure

They don't seem to have the same level of detail online, however this may help a bit.
