1 US Gallon = 3.78541178 liter
1 hour = 60 minutes
Flow in gpm * 3.7854 * 60 = Flow in lph
You can't, PSI=Pounds Per Square Inch, and GPM = Gallons Per Minute the first is a static pressure like volts and the second is a rate a flow rate like amps.
1 US gallon per hour = 0,016667 US gallons per minute
1 US gallon per minute = 60 US gallons per hour
366 gph to psi
[object Object]
Multiply psi x 0.07 to get atmospheres.
By gph I suppose you mean gallons per hour. Pumps are made with different discharge characteristics, you should have with the pump a graph showing the discharge head or pressure against flow rate. If you only have pressure quoted, 1 bar = 14.5 psi = 30 ft head of water (roughly), so 1 psi = 2 ft water head. If you don't have the characteristic graph you will have to go back to the makers for it
No, It is not possible as they measure different things. Pounds is a measurement of force and psi is a measurement of pressure. This problem is similar to asking if feet can be converted to gallons.
1 ATM = 101325 Pascals 1 Pascal = 1/101325 ATM
The lb (Pound) is a unit of mass (sometimes called weight) and the psi (pounds per square inch) is a unit of pressure. I take it that you need to calculate the pressure of a number of pounds on a certain surface. You may find the suggested web site helpful. You can't convert pounds to pounds per square inch (psi). One is force and one is pressure. If you know the area over which the force is spread, then you can divide the force by the area and get pounds per square inch (psi).
14.5 psi
400 gph, 45 psi
Multiply psi x 0.07 to get atmospheres.
Multiply psi by 0.006894759086775369 to convert from psi to MPa. ex: 1000 psi = 1000 x 0.006894759086775369 = 6.89 MPa http://www.chapelsteel.com/psi-mpai.html
Multiply by 2.03625437 to convert from psi to inches mercury. Multiply by 0.49109777 to convert from inches mercury to psi.
1 bar = 14.5 PSI
752 Torr = ~14.54 psi
110 - 130 Scfn is what in psi
1 psi = 64984.65 Pa Therefore 50 MPa = 769 Psi
Multiply psi by 144 to get psf.
95 psi = 6.6 bar
