An emergency fire control system on a public building has a pressurized tank on top of the bulding and is connected directly to a valve at street level in the side of the building via a standpipe. The air pressure maintained above the waer level in the tank is 5psig, and the water level in the tank is 50 ft above the valve. What is the pressure in psig at the valve if the water temperature is 70 degrees F?
