It was my impression that this book was the ultimate reference for calculating flow resistance through fittings. Perhaps someone who studied this text might have some comments on how Idelchik handles these issues. Look again and you will see that Schedule 40 pipe only applies to Class and less; Schedule 80 pipe for Class and and so on.

The way I interpret this is that you would have to adjust the K value using equation for the different internal diameter if you were using a schedule 80 pipe in a Class or less application.

For example, 2" pipe, schedule 80 has an ID of 1. If you were using schedule 80 pipe in a Class application, the K value would have to be adjusted accordingly because the K values are published for the schedule 40 Class pipe, not the schedule 80 Class pipe; different velocities. BTW, I am doing a project for vegatable oil tank farm expansion and we are using a smaller diameter SS pipe than I would normally choose for our flow rates asked for by the client because in their experience, there is essentially very little effective friction at all, the stuff just glides right down the pipe!

RE: Crane fittings vzeos Mechanical 22 Dec 06 There seems to be a good deal of confusion about the relationship and use of the friction factor and the K-factor. Inspection of equations , , and on page of Crane TP see below should clarify the issue. It should be completely evident that the link between the friction factor and the K-factor is established by virtue of the Darcy equation and that f is the Darcy friction factor.

The purpose for inventing a K-factor and doing this algebraic manipulation is to develop a dimensionless group to be used for model scaling and to generalize experimental findings based on a limited number of experimental results. The Darcy friction factor can be obtained using your favorite charts or equations.

There is no special significance given to the fT values provided on page A Once the K-factor value is determined for a valve or fitting it can be equated to a hypothetical pipeline having particular values for the parameters f, L and, D by using equation The values for the parameters of the hypothetical pipe are not set in stone.

What is the length of 2. RE: Crane fittings.
