Question

The water pressure is 40,000 Pa on the ground and 10,000 Pa on first floor. Find the height of the first floor. Given the density of water at 1000 Kg/m³, g =10 m s⁻².

G1 Physics · Accepted Answer

Step 1: Use hydrostatic equilibrium, P₂−P₁ = ρgΔh; in an accelerating fluid replace g by the effective acceleration where required. Step 2: Equate pressures at the same horizontal level or integrate pressure over the stated surface. Applying these relations to the given data gives 3. Final answer: 3.
