Transport Model as we have seen, a number of Fow phenomena can be described by the general equation I = Δ V / R fow rate or fux driving potential resistance

Examples electrical circuit with resistor driven by battery: I = E / R fuid circuit driven by pump: I = Δ E pump / R heat transFer between two reservoirs: P = Δ T / R

Linear Transport - PRS Which statement is not true about linear transport systems? A. If you double the driving force (voltage, temperature difference,. ..) , the current doubles. B. If you double the resistance, the current is halved. C. In linear transport systems, energy is being transformed from one type to another. D. For both ±uid ±ow and electrical circuits, the power dissipated due to the resistance depends linearly on the driving force (pump energy, battery voltage). E. All of the other statements are true.
