Need help with something EASY

Naoman

Hello, I am a student working on my senior design project. I need to model a simple fluids problem: cold engine oil being sucked out of an oil pan through a hose (or pipe) by a vacuum.

The volume (~5 quarts) and viscosity of the oil are set, the drain hole is of set diameter (0.3"), the pipe is 0.5" in diameter and of set length (5'). The pressure drop from the vacuum is going to vary, and I want to determine the flow rate out of the pipe due to the vacuum (in order to find the total time for oil removal). If I cannot get a relationship graph of flow rate vs. pressure drop, it is ok to set the pressure drop to, say 5 psi.

I need this for validation purposes of the hand-calculations, but I have no experience in CFD. I tried using the Fluent/GAMBIT software provided on campus and learning how to use it online, but I got practically nowhere. I desperately need a CFD model of this ASAP, if someone could please help me with this. I would really appreciate it.

Thanks
