Here we have listed the essential formulas related to the ‘All formulas of mechanical properties of fluids’.
It is the force exerted on a unit area of the surface of a fluid. It is expressed as:
Below the surface of the fluid, at depth ‘h’, the hydrostatic pressure is expressed as: Where ‘g’ is the acceleration due to gravity.
The pressure at any point of fluid is the sum of atmospheric pressure & pressure exerted by all fluid above that point. This can be expressed as:
It states that, the pressure exerted by a gas is inversely proportional to the volume occupied by it at constant temperature.
It states that, for an ideal gas, the volume is directly proportional to the absolute temperature at constant pressure.
Where p is the fluid pressure, v is fluid velocity, ρ is fluid density and h is height of the container
The property of a fluid which opposes relative motion between two layers is known as Viscosity and is expressed using the formula:
The viscous force on a spherical body with radius r, falling through a liquid of viscosity is expressed as:
It is defined as the volume of a liquid flowing through a capillary tube per second when its end are maintained at a pressure difference of P is:
