A sealed cylindrical drum has internal diameter 0.58 m and internal height 0.85 m. It weighs 0.25 kN when empty and 2.20 kN when completely full of an oil.

  1. (a)
    Calculate the density of the oil.
    [4]
  2. (b)
    Calculate its specific weight.
    [2]
  3. (c)
    Calculate its relative density, and state whether it would sit above or below water in a tank if the two did not mix.
    [2]
  4. (d)
    The oil is instead blended with an equal volume of a miscible liquid of RD = 1.00. Assuming the volumes are additive, find the RD of the blend.
