# What is the excess pressure inside a liquid jet?

$\\ \Delta P = \frac{2T }{d} \\ \\ Where \ \Delta P \ is \ the \ excess \ pressure\ and \ d = diameter \ of \ jet$

Pressure depend on surpacen tension

P=2T/d

pressure inside a liquid jet in excess of atmostpheric pressure . for example if aglass tube of samll diameter is partially immersed in water , the water will wet the surface of the tube ant it will rise in the tube to some height above the normal water surface .
