Task id10777
Determine the pressure loss when water moves in a steel pipeline with a diameter d = 0.1 m and a length L = 200 m, consisting of sections with lengths l = 10 m, welded by electric arc welding with a thickness of the joint protrusion above the inner surface of the pipeline d = 3 mm. Compare with pressure losses in the same pipeline without taking into account joints, if water flow Q = 0.05 m3/s, temperature 20°C.
