Water pump question

[Emmerich]

Does anybody know what a typical water pump can flow in gallons/minute? I am talking about an engine driven pump, not electirc. I know it varies with engine speed, I am wondering what the maximum rate can get to.

On a related question, is there an *easy* way to meausre the output of your water pump, without setting it up on a test bed of some sort?

Any info is appreciated.

I seem to recall that the N-series Cummins could come with either a 90 or a 150 gpm water pump depending on its intended application. To measure, you could install a flow meter in a radiator hose.

Any idea where such a flowmeter can be had? Wouldn't it restrict the flow too much?

The one I was using at the time was like a fairly large piece of pipe with a little turbine in the center. I don't think it had much effect on flow. It came from the intrumentation shop at the test facility where I was working at the time. I don't remember who makes them.

If you were really serious about an in-line flowmeter, you could check with the folks at Omega Engineering. They might have a solution, but "easy" wouldn't necessarily come cheap.

Emmerich, is this for your V-8 powered Porsche project?
