Question

Map a Sapling Learning macmillan learning 2.30 x 105 gallons of turpentine (SG 0.863) is stored in a 29.0-ft tall storage tank. What is the total mass of the liquid in the tank? Number lb 1.6565 x 10 What is the pressure at the bottom of the tank? Incorrect. Number The pressure at the bottom of the tank is equal to the pressure above the liquid level (since the tank is not pressurized, this is equal to the atmospheric pressure) plus the hydrostatic pressure. 403.93 lb in P Po+ pgh atm pgh Pay attention to the unit conversions during the hydrostatic pressure conversion. The density of turpentine is given in terms of pounds-mass but the pressure is in terms of pounds-force, so it is necessary to convert between the two units by dividing by 32.174 lb ft s 1 lb Remember to convert between feet squared and inches squared, and that g 332.174 ft/s

Explanation / Answer

Find pressure at bottom:

P = Patm + rho*g*h

h = 29ft = 29*12 = 348 ft

P = 14.7 + 0.863*63.5*348 /32

P = 596.4148125 lbf/in
