Hydrostatic+Pressure

=Hydrostatic Pressure= toc Hydrostatic pressure is the pressure exerted by a fluid at equilibrium due to the force of gravity. where //ρ// is the fluid density (kg/m3), g is acceleration due to gravity, h is height of column.

Starling equation
The Starling equation reads as follows:

where: By convention, **//outward force is defined as positive, and inward force is defined as negative//**. The solution to the equation is known as the net filtration or net fluid movement (//J////v//). If positive, fluid will tend to //leave// the capillary (filtration). If negative, fluid will tend to //enter// the capillary (absorption).
 * ([//P////c// − //P////i//] − σ[π//c// − π//i//]) is the net driving force,
 * //K////f// is the proportionality constant, and
 * //J////v// is the net fluid movement between compartments

According to Starling's equation, the movement of fluid depends on six variables:
 * 1) Capillary hydrostatic pressure ( //P////c// )
 * 2) Interstitial hydrostatic pressure ( //P////i// )
 * 3) Capillary oncotic pressure ( π//c// )
 * 4) Interstitial oncotic pressure ( π//i// )
 * 5) Filtration coefficient ( //K////f// )
 * 6) Reflection coefficient ( σ )

Typical values
