Flow through a tube

As an initial list: oil viscosity ( at temperature ) oil density length of 3.5mm pipe length of 12.5mm pipe is the joint a step or cone ( angle ) are the pipes rough or smooth. outlet pressure

How accurate do you need your answer to be ?

I use the Hazen-Williams equation but this is for water, and I don't know how it needs to be altered for changes in viscosity.

You'll need to know the oil's properties at temperature and the downstream pressure. You'll also need to know the initial flow velocity, like 0 in a reservior.

You can use the energy equation for this problem. That's bernouli's equation with a head loss and pump head terms added. You should be able to find this in any decent fluid mechanics text.

You don't need the equations, you need PipeDrop!!!
