Question One Fluids, hydrostatics (a) Complete the following table (including units) Substance Density Relative Mass of 0.8 m Specific Weight Density SAE 20 Oil 730 kg (b) The hydraulic braking system of a car relies upon a brake-pedal lever applying a force to a piston of diameter 12.5 mm. the piston in turn pressurises a fluid, which applies a force to the another piston of diameter 25 mm. this in turn applies a force to the braking pad. Determine the amplification of the force by this system. Hydraulic oil Fin - Fout Long pipe Brake-pedal piston Brake-pad piston (c) A well contains fresh water to a depth of 25 m. (i) Determine the absolute pressure at the bottom of the well on a day when the atmospheric pressure is 101 kPa. (ii) Show, diagrammatically, the variation in absolute pressure with depth [3 Quiz marks]
