$ \operatorname{Specific Flux} = \frac{Flux \times TCF}{NDP} $

Where: $ \operatorname{TCF} = e^{x} $

$ x = u\left( \frac{1}{T+273} - \frac{1}{298}\right ) $

NDP = Net Driving Pressure

$ NDP = P_{feed}-\Delta \pi-\frac{\Delta P}{n+1}-P_{permeate} $

$ P_{feed} = $ RO feed pressure

$ \Delta \pi = $ Osmotic Pressure

$ \Delta P = $ Feed/Brine Differential Pressure

$ n+1 = $ Number of membrane stages

$ P_{permeate} = $ Permeate back pressure
