CE6451  FMM Important Questions

UNIT- I: FLUID PROPERTIES AND FLOW CHARACTERISTICS

PART-A

  1. Find the surface tension in a soap bubble of 40 mm diameter when the inside pressure is 2.5 N/m2 above atmospheric pressure.
  2. Determine the minimum size of glass tube that can be used to measure water level, if the capillary rise in the tube is not to exceed 2 mm. Take surface tension of water in contact with air as 0.073575 N/m.
  3. A soap bubble is formed when the inside pressure is 5 N/m2 above the atmospheric pressure. If surface tension in the soap bubble is 0.0125 N/m, find the diameter of the bubble formed.
  4. The converging pipe with inlet and outlet diameters of 200 mm and 150 mm carries the oil whose specific gravity is 0.8. The velocity of oil at the entry is 2.5 m/s, find the velocity at the exit of the pipe and oil flow rate in kg/sec.
