Find the required diameter of a droplet of water in order to have a pressure of 1 kPa within it, relative to pressure outside it. Use surface tension, a = 0.514 N/m.

The manometer pressure at pipe A is about 30mmHg and the initial differential reading of Mercury is 0.30 m as shown.Calculate the absolute pressure at pipe B.

Determine the height h of the column of mercury in the tube if the level of water in the tube is 0.2 m and the dimensions of the oil and the water listed in the diagram. Let poil = 900 kg/m³, pwater = 1000 kg/m³, PMercury = 13,500 kg/m³. A 0.4 m Oil B 0.3 m h Water Mercury 0.2 m

A glass jar weighs 30 g. The jar weighs 80 g when filled with water and it weighs 105 g when filled with syrup. Calculate the specific gravity of the viscous liquid.
