Pressurized tank / safety shower
Pressurized tank / safety shower
(OP)
Greetings,
I'm looking for feedback on method.
We have a 400 gallon tank (160psi mwp)and a safety shower with a required pressure of 30 psi. There is 5 psi of pressure loss between the tank and shower. We use 2 air cylinders (80 ft^2 @ 2200 psi) to a regulator set at 35 psi to pressurize the tank and supply the shower for 15 minutes @ 25 GPM. (I am having a hard time finding the equations, but test data confirms)
Now if the new pressure loss is 40 psi; is it as simple as doubling the air cylinders to 4 x 80ft^2 @ 2200 psi and setting the regulator at 70 psi?
Best Regards,
