For the flow of water in the square tubes described in Problem 9.32, compute the pressure drop over a length of 22.6 m. All surfaces are copper and the duct is horizontal.

Problem 9.32

Each of the square tubes shown in Fig. 9.21 carries 0.75 m3/s of water at 90°C. The thickness of the walls of the tubes is 2.77 mm. Compute the Reynolds number of the flow of water.
