A storage barrel holds a volume of 100 gal. Waht is the load in lbf (not lbm) of the water in the barrel if it is filled to the top? Assume g=15.9ft/s^2, the density of the water is 1000kg/m^3, weight is in Newton's and 1 N = 1kg*m/sec^2.
The correct answer is 3,081 lbf, but I cannot arrive to that answer. Could you please show how with work?
