depends on where the piston is, as the force is highest when piston is at its highest position.
pipe diameter is larger than that of cylinder?
At the top, the volume is that of the cylinder + that of pipe
volume of cylinder is πr²h = π0.1²0.5 = 0.005π m³
volume of pipe is πr²h = π0.2²1.6 = 0.064π m³
total = 0.069π m³
mass of that water = 1000 kg/m³ x 0.069π m³ = 220 kg
density of fresh water at 20C = 0.998 g/cm³ = 0.998 kg/L
= 998 kg/m³ = 8.33 lb/gal = 62.1 lb/ft³
