There is a PVC pipe, with an internal diameter of 28 mm. The Reynolds number for this system is 1500. The percentage of error that represents the accuracy in the estimation of the friction factor, by the Swamee-Jain and Colebrook-White method, is in a range of (4-5)% . Hint Use 7 decimal places in calculating the friction factor and remember that the best method to estimate the friction factor is Colebrook-White. True or false?
