Using 80 psi in a water rocket strikes a balance between maximizing thrust and ensuring safety. At this pressure, the water is effectively forced out of the nozzle, generating strong propulsion, while minimizing the risk of structural failure in the rocket. Higher pressures can increase the risk of rupture, while lower pressures might not provide sufficient thrust for optimal performance. This pressure level is commonly found to achieve good altitude without compromising safety.
40-80 psi.
Yes, definitely too high. It should ideally be 50-80 psi.
factory air pressure norm is 80 psi
Area water authority could have increased water main pressure, no or defective expansion tank in house main water line if house has a backflow preventer installed, or defective /not properly set pressure reducing valve.
The minimum water pressure in a building should generally be around 40 psi (pounds per square inch) to ensure adequate flow for faucets and fixtures. The maximum water pressure is typically around 80-100 psi; pressures above this range can cause damage to pipes and fixtures. It's advisable for buildings to have pressure-reducing valves installed to maintain safe and efficient water pressure levels.
To calculate the static pressure at a depth of 25 feet with a psi of 80, we need to consider that 1 psi corresponds to approximately 2.31 feet of water. Therefore, the pressure in feet of water at 80 psi is 80 psi × 2.31 feet/psi = 184.8 feet. At a depth of 25 feet, the static pressure would be the sum of the atmospheric pressure (typically 14.7 psi at sea level) and the pressure from the water column. In this case, the static pressure at 25 feet is approximately 80 psi, assuming the measurement is taken at that depth.
Optimal household water pressure should be between 40 psi - 80 psi. If water is supplied by public water usually they supply the minimum pressure. If you have more than 80 psi, a pressure reducer is recommended.

Yes if your water pressure is over 80 PSI No if your water pressure is under 80PSI (if its right at 80 psi you be the judge) If you have high water pressure and need to install one then make sure you buy a name brand other wise you are taking a chance of it failing and having no water pressure at all.
Over 20 psi at idleUnder 80 psi while driving Over 20 psi at idleUnder 80 psi while driving
Normally between 40 and 80 psi, but mine runs about 90....
between 20 and 80 psi between 20 and 80 psi
Around 80 psi cold at startup, and 40 psi at normal operating temperature.
