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.

What is the static pressure of 25' with a psi of 80?

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.


What should be the minimum pressure in domestic water pipeline?

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.

Do you need a water pressure regulator?

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.
