WebUse the equation for the engine pressure. EP = DNP ± HG (or HL) +FL Step 5. Identify the DNP, the HG, and the FL. DNP = 100 psi, HG = 100 psi, FL = 30 psi Step 6. Set up the problem and solve. EP = 100 psi - 100 psi + 30 psi WebWater Pressure Equations, Conversions, Formulas, and Calculations: Feet head (of water) x .433 = Pounds per square inch (PSI) Feet head (of water) x 0.3049 = meters head (of water) Feet head (of water) x 0.0295 = atmospheres. Feet head (of water) x 2.988 = kiloPascals. Meters head (of water) x 3.28 = feet head (of water)

So, it turns out that back in 1965, the pump sales rep was trying to show me the correct pump for my application. Differential pressure Allow me to refine a couple of points: WebKnowing the required static head is useful when selecting pumps to lift water to specific heights. Assumes water temperature of 60F / 16C. Head formula – Imperial. 27.72 inches of water = 1 psi. 1 foot of water = 0.433 Psi. Example. 3 feet X 0.433 = 1.299 Psi. Head Pressure – Metric. 10 Kpa = 1.45 Psi. submarine launched icbms
