A 100-m long horizontal pipe carries water at an average velocity of 2.5 m/s. The required pressure drop, deltaP, across the length of the pipe required to achieve this is 1.5 x 10^5Pa, and the surface roughness to diameter ratio of the inside of the pipe is k/D= 0.004. What is the diameter of the pipe?

The only current example on chegg of this problem is wrong.
