Help: How to calculate Ha

Thread Content

Yes, in the equation, is Ha equal to the atmospheric pressure in the installation area divided by the density of water at that atmospheric pressure and g, or is it divided by the density of water under standard conditions, which is 1000, and g? The unit is mH2O. Could some experts please take a look? Thank you!

Ha is the atmospheric pressure (absolute pressure, in Pa) in the installation area divided by 1000 and g (9.81), with the unit being mH2O

This formula is too complicated; it’s recommended to simplify the calculations!
