Question

Three lines C1 (L1 = 100 m; D1 = 800 mm and ε1 = 0.24 mm), C2 (L2 = 150 m; D2 = 60 mm and ε2 = 0.12 mm) and C3 (L3 = 160 m; D3 = 40 mm and ε3 = 0.20 mm) are connected in series one after the other to transport water (ρ = 1000 kg / m3, ν = 1.02x10-6 m2 / s). If the energy difference at the ends of the system is 130 kPa and the difference in height 5 m, you are asked to determine the flow carried

Answer 1

● So the discharge will be 0.00488 litre/sec or 4.88 ×10^-6 m3/sec.
