The traditional "Moody-type" pipe friction correlation in Chap. 6 is of the form 2APD f = pVL (pVD и "D, where D is the pipe diameter, L the pipe length, and e the wall roughness. Note that pipe average velocity V is used on both sides. This form is meant to find Ap when V is known. (a) Suppose that Ap is known, and we wish to find V. Rearrange the above function so that V is isolated on the left-hand side. Use the following data, for e/D = 0.005, to make a plot of your new function, with your velocity parameter as the ordinate of the plot. 0.0356 | 0.0316 | 0.0308 pVD/u | 15,000 | 75,000 | 250,000 | 900,000 | 3,330,000 0.0305 0.0304 (b) Use your plot to determine V, in m/s, for the following pipe flow: D = 5 cm, e = 0.025 cm, L = 10 m, for water flow at 20°C and 1 atm. The pressure drop Ap is 110 kPa.
