Water is supplied through the pressure pipe with a diameter of d and length l at a temperature of 100 ° C in the amount of Q. There are local resistance on the pipeline: 4 ordinary valves, 1 suction valve, 1 non-return valve, 3 elbows welded at an angle α.
Determine the pressure loss on the hydraulic resistance in the pipeline and the pump discharge pressure if water is supplied to a height of h.
Pump pressure expressed in MPa, physical and technical atmosphere.
Given: d = 115mm = 0.115m; l = 2100m; Q = 37l / s = 0.037m3 / s; h = 70m; α = 400.
Define: Σhw, pH
