Q1. A 4 ft diameter cylindrical tank lays on its side with its central axis horizontal. A 1.5 ft diameter pipe extends vertically upward from the middle of the tank.

Oil (Specific gravity = 0.9) fills the tank and pipe to a level of 8 ft above the top of the tank. What is the hydrostatic force on one end of the tank? What is the total hydrostatic pressure force on one side (semicircle) of the tank if it is 10 ft long.
