Consists of the pressure the air exerts in the direction of flow (Velocity Pressure) plus the pressure air exerts perpendicular to the plenum or container through which the air moves. (static pressure) In other words:
PT = PV + PS
PT = Total Pressure
PV = Velocity Pressure
PS = Static Pressure

Force (lbs) = Pressure (psi) x Area (in2)Pressure=Force/Area
pressure is force divided by area. If area is 1.6m^2 then pressure is 560/1.6 = 350 pascals
the area over which the force acts
What's the formula to calculate bottom hole pressure
Pressure = Force / Area
There is no friction IN static electricity. However static electricity can be caused BY friction.
Inlet pressure/discharge pressure
The CFM of the equipment are given, how to calculate Static Pressure for it.
Air has a pressure, but not a suction pressure. Air pressure is measured with a barometer, you do not calculate it. Suction pressure is a concept which applies to a pump. Suction pressure = static pressure + surface pressure - vapour pressure - friction pressure.
pressure=force/area
You can calculate pressure based on Piezometers but without a measurement I don't know that it is possible. I would say you can calculate the pressure force by P=Z(bar)*gama(water)*Area(of the channel).
itive of pressure=
It really depends, based on what data you want to calculate pressure. For a start, you can use the basic definition of pressure, as force divided by area.
