this will depend on the area of the outlet of the hose
Pressure doesn't change when you change substance, 120 PSI in water equals 120 PSI in air.
1 psig is equivalent to 51.71 mm (2 in) of mercury or to approx 700 mm (27.5 in) of water. Technically one cannot have apsig. Psig represents a pressure reading of the pressure above normal atmospheric pressure of 14.7 psi. You mean a psi.
80 psi or less
It depends partly on what is dirtying the concrete. If it's oils stains and other motor vehicle fluids, you need at least 2,500 psi and special soaps.
Normally between 40 and 80 psi, but mine runs about 90....
7000 PSI
Inches of water x 0.03613 = psi
About 130 psi at 300 feet of water depth.
35 inches of water = 1.26 psi
There are about 34.6 psi in 15 feet of water.
At 5,400 feet of water depth the pressure is about 2,341.1 psi
10 psi.
138.60ft 2.31ft of water= 1 psi
The psi pressure rating is good for any fluid. The fluid may be water or compressed air. -Destroyer of Babylon
Pressure doesn't change when you change substance, 120 PSI in water equals 120 PSI in air.
27.71 inches of water column equals 1 psi
At 300 feet of water depth the pressure is about 130 psi
