1. how deep of a hole would have to dug so that the pressure down there would be 29.4 psia.2. at the bottom of 30 ft of liquid is 50 psia, what is the density in lbs/ft cube3. a liquid 30 lbs/gal, exerts 35 psig how deep is it4. pure water equally dissociates into H+ and OH- ions, for a pH of 7. However what would be the concentration of the hydroxyl ions ( ions-) if the pH is 12.
1. Pressure is given byP=ρghWhere ρ is densityg is acceleration due to gravityh is depthP = 29.4 psia = (29.4 x 6894.757) Pascals = 2.03 x 105 Kg/(ms2)g = 9.8 ms-2Density of air, ρ = 1.2...
