Question:

A mass (or load) acting downward on a piston confines a fluid of density ρ in a closed container, as shown in Fig. 13-2. The combined weight of the piston and load on the right is 200 N, and the cross-sectional area of the piston is A = 8.0 cm². Find the total pressure at point-B if the fluid is mercury and h = 25 cm (ρ_Hg = 13 600 kg/m³). What would an ordinary pressure gauge read at B? B y Fig. 13-2
