# Calculate Static Pressure?

## Answer

It is useful to calculate static pressure to find the diameter of heating and cooling ducts, and other HVAC factors. Knowing the static pressure also allows heating and cooling equipment professionals to determine duct velocity, the air mixture, and any loss of friction. To calculate these factors, most HVAC professionals now use Excel spreadsheets. The complicated calculations necessary to determine static pressure would take an inordinate amount of time without the use of available software and spreadsheets.
