PIPE COILS
- Thread starter finite
- Start date
The pressure loss is basically dependant on the total length of pipe - i.e. the amount of internal surface area providing frictional resistance. In your applications the bend radius is large, so you are not likely to get secondary turbulence at the fittings - because there are none.
If you were working with a tube bundle - such as a heat exchanger, then you would have short radius elbows to provide added friction.
If in doubt - do a test with a garden tap and hose pipe. You can coil that to a similar condition and you will quickly find if your pressure losses are more than calculated in straight pipe.

I agree with Johnp above.... the problem is basically on of a straight pipe.... suggest you purchase that an "old faithful" that I have in my library.... Crane Technical Manual #410..... AMAZON must have it.... also suggest that you try the superb fluid calculators on
Good luck !!! MJC
