संकल्पना:

पाइप में घर्षण के कारण होने वाला शीर्ष नुकसान:

\({h_f} = \frac{{f'L{V^2}}}{{2gd}}\)

f’ = घर्षण गुणांक, L = पाइप की लम्बाई, V = पाइप में तरल पदार्थ का औसत वेग, g = गुरुत्वाकर्षण के कारण लगने वाला त्वरण, d = पाइप का व्यास

गणना:

दिया गया है:

d = 100 mm, f' = 0.05, L = 100 m, V = 4 m/s

पाइप में घर्षण के कारण होने वाला शीर्ष नुकसान:

\({h_f} = \frac{{f'L{V^2}}}{{2gd}}\)

\({h_f} = \frac{0.05 \times 100 \times 4^2}{{2 \times 10 \times 0.1}}=40\;m\)
