Mass flowrate with time and climbing time.
 

Hello guys,
I'm trying to find mass flow rate and climbing time of oil,problem consists of oil sump and rotating components.I need to find mass flow rate at outlet and climbing time.So the given boundary conditions for inlet are RPM(3000),0.624 bar ,density 890 kg m3, dynamic viscosity 4.45 103 kg/ms.
I need to know how to fill the oil bottom tank with oil and all the other conditions to be given to get data for massflowrate vs time graph and climbing time.thankyou
