Calculate the minimum engine power Ne, necessary to drive the water pump in the amount of Q = 300 l/min from the well at the depth h-6m to the tank located at the height h3=18m from the pump by pipe with diameter d=5cm. The length of the suction pipe h,+h+1=12m and the discharge pipe l2+h3+13=24m. Local resistance coefficients -9.3, k=0.3, -1.0, pump efficiency n=0.76, pressure pg=1500hPa, height h=2m. h3 2 8 E od
