The Osmotic Pressure of Macroions.

AGAINST THE VALIDITY OF THE CLOSED SYSTEM MODEL FOR CALCULATING OSMOTIC PRESSURE

This paper criticizes the model and the new definition for osmotic pressure given by Parsafar et al. [J. Sci. I. R. Iran, Vol. 10, No. 4, 233 (1999)]. The model is a closed system containing 1 kg of solvent plus m mole of solute at constant temperature and under pressure P0 + ? where P0 is the standard pressure and ? is the osmotic pressure of the corresponding m molal solution. While the total...

CALCULATION OF OSMOTIC PRESSURE USING A CLOSED SYSTEM MODEL

In this work we have used a closed system model to derive an analytical equation for the osmotic pressure of two component electrolyte and non-electrolyte solutions. In order to do so, we have used an equation of state, known as the dense system equation of state (DSEOS), for the model system. Based on the model, a new definition is given for the osmotic pressure of a closed system. Good ag...

Osmotic pressure of the serum proteins.

The osmotic pressure of the serum proteins (colloid osmotic pressure [COP] or "oncotic" pressure) is only one of the four Starling forces (plus the capillary permeability coefficient) which affect the net filtration of fluid from the capillaries. The COP will vary with the concentration of total serum proteins, but more so with the specific pattern or composition of the protein components, espe...
