Please solve for (c) and present the full steps
![Consider water flow through a pipe 6 m long and internal diameter 300 mm. The head
loss due to friction at the pipe surface is known to be 6 m. The roughness surface is
known to be 3 mm. Take the ambient temperature as 15 °C.
(a) Calculate the average flow velocity,u and the flow rate, Q in the pipe. Since the
friction factor f is unknown, assume it to be 0.04, as a first guess.
(b) From results of (a), use the Moody diagramme to find a more accurate friction
factor, and hence a better average flow velocity and flow rate.
(c) Consider a different approach, using the Darcy-Weisback equation and the
Colebrook equation, to find the flow rate in the pipe. Derive a general equation that
gives the flow rate directly. Then substitute in the numerical values to find a number for
Q for this problem.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6cab4df3-cd5b-403c-805a-486c155923ed%2Fb1e6993c-53dc-4468-a58c-68c56cc6fae7%2F1nhjq7s_processed.jpeg&w=3840&q=75)
