About 87.6 psi
House water pressure should be around 50-60 psi.
50 psi
this will depend on the area of the outlet of the hose

Yes, definitely too high. It should ideally be 50-80 psi.
Automatics can function in the 50 -150 psi range.Automatics can function in the 50 -150 psi range.
the weight of the water above. water in a 1" pipe 100' tall is 43 psi @ base of pipe. water in a 50' tank 100' tall is 43 psi @ base of tank. h x .434 = psi
12 to 15 psi @wot
50-75 psi
gpm and psi are two different measures that are not directly related, though a change in one will affect the other. To get the pressure at a certain point in your piping, you would need to measure it. Or, if you know that your pump is rated for 50 gpm at 80psi (1 foot water column = 2.31 psi) and your pump is lifting a column of water 15' (34.65 psi), then you should have about 45 psi residual. If you have long runs of horizontal pipe you may need to add some for pipe friction also.
Flushometer type needs at least 30 PSI to operate semi decently 50 PSI or more would be ideal
