The gauge pressure on her (water density = 1000 kg/m³, $g = 9.A hydraulic lift uses a small piston (area 1 cm²) and a large piston (area 100 cm²). To lift a 1000 kg load, tTwo liquids of densities $\rho_1$ and $\rho_2$ exert the same pressure. The ratio of their column heights $h_1**Hydrostatic paradox** explains why:A capillary tube of radius $r$ dipped in a liquid of surface tension $T$ and density $\rho$, contact angle $\tA steel ball of radius 0.3 mm falls at 2 m/s through glycerine ($\eta = 0.833$ N·s/m²). The viscous drag is:A liquid flowing through a tube has Reynolds number $R_n = 500$. Its flow is:The pressure at the **top of a column of water** open to atmosphere is approximately:The pressure at a depth of 200 m below the ocean surface (sea water density ≈ 1030 kg/m³, $g = 10$ m/s², $p_0 **Newton's law of viscosity** gives the viscous force as $F = \eta A (dv/dx)$ where $dv/dx$ is the **velocity Atmospheric pressure at the surface of the Earth is supported by a column of mercury approximately 76 cm tall.A car of mass 1000 kg traveling at 50 km/h has hydraulic brakes with master cylinder area $\pi (0.5\,\text{cm}The terminal velocity of a sphere of radius $r$, density $\rho$ falling through a fluid of viscosity $\eta$ anWater rises 4 cm in a capillary of radius 0.5 mm.
