Question 2
The surface tension in a soap bubble of 50 mm diameter with its inside pressure being 2.5 N/m2 above the atmospheric pressure is
Question 3
Two slits having width 20 mm are placed 1 mm apart in a fluid having specific gravity 0 .73 . Consider the slit distance to be so small that there is a capillarity effect due to two slits. Also assume that the angle action for the glass fluid medium to be 30 degree. Find the rise of liquid in the slits. surface tension of the fluid is 0 .2 pas

Question 5
Which of the following statements are correct?
1) Depression of mercury in a capillary tube is dependent on density and surface tension.
2) Modelling of flow-induced drag on a ship is done invoking both of Froude number 30. and Reynolds number.
3) Flow of a fluid in a narrow pipe is relatable to both Reynolds number and Cauchy number.
4) Formation and collapse of a soap bubble is analyzed through employing surface tension and external pressure.
5) Flow over the downstream slope of an ogee spillway can be affected by surface tension.
