Three pipes of different lengths and diameters are connected in series as shown in the figure. If the discharge is 210 L/sec and the Manning's roughness coefficient for all pipes is n = 0.015, what should be the total head loss (HL) from point A to D (if minor losses due to sudden contractions, hm,is assumed to be 10% of the computed head loss due to friction, hf)? (Hint: NOTE: HL = hf + hm) A B C D 450 mm – 1800 m 300 mm - 1500 m 250 mm - 800 m
