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.
Steady State? generalized fow (linear transport) equations work in steady state what about cases where we are not in a steady state? (changing systems) two common kinds oF change: exponential change oscillations
