Defination - Pressure head (h) is defined as the height of a column of liquid of specific weight (w) required to give a pressure difference of p. Pressure head is a linear quantity and i…
Statement - Pascal's law states that if the fluid is at rest, the intensity of pressure at a point will be same in all directions. Proof - Consider a small wedge shaped element in …
Capillarity is defined as the phenomenon of rise or fall of a liquid in a thin tube ( capillary tube) relative to the adjacent general level of liquid. It is a surface tension effect and d…
