The pressure in a cylindrical jet of a liquid 5.0 mm in diameter is 30 N/m²
in excess of the ambient pressure. Calculate the surface tension of the liquid.

If the surface tension of water in contact with air is 0.075 N/m, what correction need to be applied towards capillary rise in the manometric readings in tubes of 3 mm diameter?
