For the system described in Problem 9.24, compute the pressure difference between two points 30.0 ft apart

Question:

For the system described in Problem 9.24, compute the pressure difference between two points 30.0 ft apart if the duct is horizontal. Use e = 8.5 Ã— 10^-5ft.

In Problem

Water at 90°F flows in the space between 6-in Schedule 40 steel pipe and a square duct with inside dimensions of 10.0 in. The shape of the duct is similar to that shown in Fig. 9.10. Compute the Reynolds number if the volume flow rate is 4.00 ft³/s.
