WebThis constant converts a foot of head of water into pressure: Head in feet of water divided by 2.31 equals pressure in psi, and pressure in psi times 2.31 equals head in feet. How do u calculate pressure? Pressure on surfaces . To calculate pressure, you need to know two things: Pressure is calculated using this equation: pressure = force area. WebPressure can be measured either as part of a scale (e.g. bar, pascals, psi) or in terms of the height of a fluid (e.g. metres of water). The higher the height of liquid, the greater the pressure it exerts at it’s base. Pressure gauges typically incorporate scaled measurements whereas pump performance is measured by its head – ie what height ...
