Subtopic: Fluid Mechanics in SWCE

Question Statement:

A pipeline of length $L = 500\text{ m}$ and diameter $D = 0.25\text{ m}$ has friction factor $f = 0.03$. A valve in the line has minor loss coefficient $K_L = 10$. The equivalent length of pipe for this valve $L_e = K_L D / f$ in meters is (rounded off to one decimal place):

Answer Key:

83.3

Step-by-Step Solution & Explanation

$L_e = \frac{10 \times 0.25}{0.03} = \frac{2.5}{0.03} = 83.33\text{ m}$.
