For both situations described in Problems 9.16 and 9.17, compute the pressure drop that would occur over

Question:

For both situations described in Problems 9.16 and 9.17, compute the pressure drop that would occur over a distance of 250 ft of horizontal pipe.

In Problems

Repeat Problem 9.16 for the same conditions, except that the inside of the pipe is roughened by age so that ε = 5.0 × 10-3. Plot the results on the same graph as that used for the results of Problem 9.16.

Repeat Problem

Using Eq. (9€“3), compute several points on the velocity profile for the flow of 400 gal/min of water at 50F in a new, clean, 4-in Schedule 40 steel pipe. Make a plot similar to Fig. 9.7 with a fairly large scale.

For both situations described in Problems 9.16 and 9.17, compute
