Webfeet of pressure head. Prior to applying this requirement, I calculated that the pressure head at point 3 was 40 feet, we are missing 29 feet. We must now calculate the total head of the pump that will produce the value of 69 feet at point 3 at the flow rate required. Using equation [5] and with the value of H X (69 feet), we can then calculate WebPressure to Head Formulas: Imperial Units: H= (2.31 * (P)) /SG where: H= Head, ft. P= Pressure, psi. SG= Specific Gravity. SI Units: H= (10.2 * (P)) /SG where: H= Head, m. P= Pressure, bar. SG= Specific Gravity. Convert from Pressure – Pounds per Square Inch (psi) to Head of Water in Feet (ft h2o)
