Applied Pressure Driving Force - (Measured in Pascal) - Applied Pressure Driving Force is defined as the force or pressure that is intentionally exerted or applied to induce or facilitate process.
Membrane Flow Resistance of Unit Area - (Measured in 1 per Meter) - Membrane flow resistance of unit area is defined as the measure of the resistance that a membrane presents to the flow of a substance through it, normalized by the area of the membrane.
Liquid Viscosity - (Measured in Kilogram per Meter per Second) - Liquid viscosity is defined as the measure of a fluid's resistance to flow or its internal friction when subjected to an external force.
Flux through Membrane - (Measured in Cubic Meter per Square Meter per Second) - Flux through membrane is defined as the rate of movement or transfer of a substance per unit area across a porous barrier known as a membrane.

## Pressure Driving Force in Membrane Formula

Applied Pressure Driving Force = Membrane Flow Resistance of Unit Area*Liquid Viscosity*Flux through Membrane
ΔPm = Rm*μ*JwM

## By what factors is the pressure in the membrane affected?

The temperature of the feed water. The higher the temperature of the feed water, the faster the water molecules move, which can increase the rate of water permeation through the membrane. This means that less pressure is required to force water through the membrane when the temperature of the feed water is high.
The surface area of the membrane. The larger the surface area of the membrane, the more water can pass through the membrane at a given pressure.
The thickness of the membrane. The thicker the membrane, the more difficult it is for water to pass through the membrane, which means that more pressure is required.
