company has several sensors in storage silos to detect the total pressure in the silos to ensure the tanks will not leak. Each tank is designed to withstand a maximum total pressure of 5.8 atmospheres​ [atm]. An engineer wants to use one of the silos to store liquid nitric​ acid, which has a density of 97​ pound-mass per cubic foot ​[lbm​/ft3​]. If the tank is filled to a depth of 80 feet​ [ft], how much surface pressure in units of atmospheres​ [atm] can be applied to the top of the liquid inside the tank without exceeding
