Answer to Question #261883 in Civil and Environmental Engineering for Aber Caroline

Question

A pipe of 40 mm bore conveys air at a mean velocity of 21.5 m· s−1. The density of the air is

1.225 kg ·m−3 and its dynamic viscosity is 1.8 × 10−5 Pa · s. Calculate that volume flow rate of

water through the pipe which would correspond to the same value of friction factor f if the

dynamic viscosity of water is 1.12 × 10−3 Pa · s. What type of flow is exhibited in this pipe?
