90 degree fitting on pump?

post #1 of 9
Thread Starter 
hey guys so im thinking about putting a 90 degree fitting on the inlet of my mcp350 with a top, and somebody said thats bad, but i looked how bits power cuts theri 90 degree fitting and i came to the conclusion that the corner actaull has a wider path that way the flow is not abstracted,
please help me decide for sure?

Ok just imagine you are driving your car is it faster to drive on a straight road or a curvy road? This is the same thing you should avoid using 90 degree turns as much as possible.

Even if the corner were the same width it would not affect flow. It's about size, not shape.

Cars are much different. Sure there's a slight reduction but it's very small.

you are completly wrong, the water will flow no matter what how many turns it had, for example take a tube fill it with water, and dump it, then bend the tube a little bit and let the water out, time it, u will notice that the water wll leave at the same time, with cars you have velocity and tires you take into account, with water as long as the path is the same size you should be fine,


am i right?

i seen a test here on ocn, it took over 30 right angle fittings to drop the flow down like 1 unit... and like 90 to drop the temps by 1*c IIRC

It will effect the flow. That was the question. I remember that test and actually found it. Here is the bottom line:
Quote:
Elbows and fittings do cause some restriction, but it's very much fractions of a degree and impacts flow rate much more than it does temperature.

So again if I can avoid it I would avoid it, if not it's not a biggy!
