Answer to Question #49031 in Mechanics | Relativity for Apprentice Learner

Question

The pipe in question is part of a straight pipeline water flow system. The flow within this system is due to ΔP (Pressure drop) across the length of a pipe (L=300m), carrying water, with diameter (D=0.2m), flowing at a rate of 1/7 m/s. The pipe is made out of cast iron (e=0.25mm)
The following data needs to be applied:
• The losses due to entrance of the pipe (k=0.5)
• The losses due to exit of the pipe (k=0.3)
• NRE = ρVD/μ
Determine the head losses in pipeline flow;
1. due to friction (both minor and major)
2. due to entrance and exit
3. pressure head losses within the system
