a) If the specific weight of a liquid is 8.1 kN/m³, what is its density? [2] b) If the specific volume of a gas is 0.70 m³/kg, what is its specific weight? [2] c) A flat plate 200 mm 750 mm slides on oil (u= 0.85 Ns/m²) over a large plane surface. What force F is required to drag the plate at a velocity of 1.2 m/s, if the thickness of the separating oil film is 0.6 mm? [3] d) Compute the capillary depression of mercury at 20°C (0= 140°) to be expected in a 1.3 mm diameter tube. Surface tension is 0.51 N/m.
