Yes.
The water pump has negative pressure in the water pipe at the bottom of the pump, and the water pipe above the pump outlet has positive pressure; the submersible pump has positive pressure in the water pipe above; the pump. Therefore, the outlet pipe of the submersible pump can be connected to the outlet of the water pump with a tee, and the water supply pipe can be shared. But the three-way connection is a bit awkward.
If the outlet pipe of the submersible pump is directly connected to the suction pipe of the water pump and the two pumps are connected in series, the water pressure head (head d water) can be increased.
Diameter 150㎜=0.15/2=0.075*0.075*3.1416=0.0177*1.5=0.027, P=9.81HQn=9.81*100*0.027*0 .8=21.19kw
Through theoretical calculation: the cross section of the pressure pipe is 0.0177 m2, the flow rate is estimated at 1.5 m/S, the flow rate = 0.027 m2/S and the theoretical energy production can be 21.19 kW, 1 h = 21.19 kW.h (degree).
