Many Other Conversions. Using this calculator a 40 foot column of Diesel would convert to 16.474 psi. Or, multiply by 100000/6894.757 = 14.503774. 1 psi = 2.3067258038528 ftH2o. Psi : Psi is the abbreviation of pound per square inch, and is widely used in British and American. P= Pressure, bar. The pressure inside the tank is 94.0 psi and the pressure at the exit is atmospheric pressure, or 14.7 psi. As we size a pumping system, we'll want to accomplish building pressure (PSI). p = 0.433 h SG (1) The relationship between PSI and feet of head is that 2.31 feet of head = 1 PSI. Pound force per square inch Foot sea water; 1 psi: 2.2500224045498 fsw: 2 psi: 4.5000448090997 fsw: 3 psi: 6.7500672136495 fsw: 4 psi: 9.0000896181994 fsw: 5 psi Feet Of Water Conversion Charts. Formula: h = 2.31 * p / SG Where, h = Head in Feet p = Pressure in Psi SG = Specific Gravity Pumps characteristic curves are often in head - feet or metres - and a conversion to pressure scales commonly used in pressure gauges - like psi or bar - may be required.. psi to foot water (60°F) (psi—ftAq) measurement units conversion. 1 psi = 6,894.76 Pascals. Converting Head to Pressure Converting head in feet to pressure in psi. So, to convert directly from bar to pounds per square inch, you multiply by 14.503774. Translated, that means that a column of water that's 1-inch square and 2.31 feet tall will weigh 1 pound. Convert pressure in psi to head in feet using this online converter based on the specific gravity. For example, to convert from bar to pounds per square inch you would multiply by 100000 then divide by 6894.757. What is the formula to calculate liquid pressure on bottom of a circular tank? 1 x 2.3067258038528 ftH2o = 2.3067258038528 Foot Of Water. Pumps characteristic curves in feet of head can be converted to pressure - psi - by the expression:. This conversion scale shows the conversion values over the 0 to 40 feet range: Pressure on bottom of circular tank. Diver must alter their habits according to … Foot Water (60°F) : Feet of Water (or called foot of Water Column, ftH2O) is an American and English low value pressure unit, now used mostly in the USA where feet and inches are the standard units for measuring distance. This example will calculate the flow rate of water draining from a tank through a pipe with cross sectional area of 0.500 square feet. Gives the pressure at a given depth in sea water. Convert from Pressure – Pounds per Square Inch (psi) to Head of Water in Feet (ft h2o) Convert psi [psi] to foot water (60°F) [ftAq] ... E-notation is commonly used in calculators and by scientists, mathematicians and engineers. Select the unit to convert from in the left box containing the list of units. Or, one-foot column of water that's 1-inch square weighs .433 pounds. Other subcategories index Games, sport, recreation index: Assuming the density of sea water to be 1025 kg/m³ (in fact it is slightly variable), pressure increases by 1 atm with each 10 m of depth. Instantly Convert Feet Of Water (ftH 2 O) to Pounds Per Square Inch (psi) and Many More Pressure Conversions Online. Conversion: Psi to Foot Of Water The base unit for pressure is pascals (Non-SI Unit) [Psi] symbol/abbrevation: (psi) [Foot Of Water] symbol/abbrevation: (ftH2o) How to convert Psi to Foot Of Water (psi to ftH2o)? SG= Specific Gravity.
