Question when designing the tank walls to be strong enough should we use pg 19. 6kpa or pabs 120. 914pa ftp io shieaes. ie eii aimhins both pg496kpa can be used to design walls i pressure variation with elevation. In a static fluid p is due togravity is the weightoffluid. 0 column of water is pressing down on. Levg where v heightcalx area a ofcolumn w lzag ezg l g. The pressure due to water at depth 2 twaterz.
