The Solution involves the use of two basic pressure formulas, namely
V= square root of 2hg where:
V= discharge velocity of nozzle or muzzle (ft/sec)
g= acceleration due to gravity (32 ft/sec/sec)
h= velocity head (ft)
An P = 0.433 h where:
P- pressure head (psi)
h=head(ft)
Take 75 psi
P= 75 psi = 0.433h
h=173.2 ft
V= square root of 2(32)(173.2)=105.3 ft/sec
PSI is a pressure measurement. FPS is a speed measurement. It's not possible to convert between the two without a great deal of additional information (it might, for example, be possible to convert a pressure measurement in the chamber of a gun to an expected muzzle velocity of the projectile, with sufficient additional information).
Do you mean FPS? If so, then it's rated at 595 FPS.
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
3,600/5,280 gives you 1 fps in m.p.h Example: 52.8 f.p.s = 36 m.p.h.
752 Torr = ~14.54 psi
110 - 130 Scfn is what in psi
1 psi = 64984.65 Pa Therefore 50 MPa = 769 Psi
PSI: It depends on how many times you pump the forearm. But Crosman says to never pump it more than 10 times. The 760 is rated at 625 FPS with a BB and 600 FPS with a pellet.
Multiply psi by 144 to get psf.
