8) A fuel tank is in the form of a rectangular box. The tank is 3 ft wide, 6 ft long, and 4 ft deep. If the tank is lled with fuel (with weight density = 60 lbs/ft3) calculate the total force due to uid pressure on the right side of the tank. (Hint: Since weight density is given so P = pgd = 6d where 5 is weight density). '31P}: a) Find the hydrostatic pressure of the slice at depth 2 ft. b) Use part (a) to nd hydrostatic force of the slice of thickness 0.5 ft at depth 2 ft. c) Find the hydrostatic pressure of the slice at depth 11:. ft
