Equilibration in two communicating oil tanks



Main
Two cylindrical tanks are connected by a hose at the bottom. Oil in one of the tanks flows into the second tank. Levels in both tanks are measured as functions of time. More…

Laws of balance
Oil_volume_1(t) = Oil_volume_1(t - dt) + (- Current_of_oil) * dt
INIT Oil_volume_1 = Cross_section_1*h1_init
Oil_volume_2(t) = Oil_volume_2(t - dt) + (Current_of_oil) * dt
INIT Oil_volume_2 = Cross_section_2*h2_init
Flows
Current_of_oil = Flow_factor*Level_difference
Relations
Level_1 = Oil_volume_1/Cross_section_1
Level_2 = Oil_volume_2/Cross_section_2
Level_difference = Level_1-Level_2
Parameters
Cross_section_1 = 0.01131
Cross_section_2 = 0.00525
Flow_factor = 0.50e-4
h1_init = 0.1405
h2_init = 0.0517
