Question

Estimate the friction losses of 50 m long PVC pipe having inside diameter 50 mm. The velocity of flowing water is 1.0 m/s and friction factor of pipe is 0.05.

• A. 10.20 m
• B. 2.54 m
• C. 3.1 m
• D. 1.52 m

Hint:

Always ensure all units are in standard SI form before substituting into the Darcy-Weisbach equation (e.g., converting the diameter from $50 \text{ mm}$ to $0.05 \text{ m}$).

Answer 1

The Correct Option is B
