For the cast Iron pipe find the friction factor of diameter \( 500 \mathrm{~mm} \). The Reynolds number is 100,000 . Kindly refer the Moody's chart. (from chapter)

Step 1 ：Step 1: Locate the Reynolds number (\(Re\)) on the horizontal axis of the Moody's chart.

Step 2 ：Step 2: Locate the relative roughness (\(\frac{\epsilon}{D}\)) on the left-side vertical axis of the Moody's chart.

Step 3 ：Step 3: From the intersection of the Reynolds number curve and the relative roughness curve, find the friction factor (\(f\)) on the right-side vertical axis.
