Under the enough big situation of upright pipe diameter, the water liquid weight vertical pressure before setting reservoir 4 to the first horizontal pressure force pipelines 6 all equates with first to fourth water liquid compression weight storage tank, 81～84 interior water liquid weight vertical pressures.
The interval height of setting reservoir to the four water liquid compression weight storage tanks 4,81,82,83,84 again is 10.33 meters, also is that the potential energy pressure difference all is 1atm (atmospheric pressure).
Estimate and do not calculate the first horizontal pressure force pipeline 6, and between first to the 5th gas-liquid pressure balance cabin 71～75, the ducts resistance resistance that different structure causes does not calculate water liquid coefficient of viscosity and surface tension yet.
When the associating water liquid weight vertical pressure of reservoir 4 with upright pressure piping 5, add the 1atm potential energy pressure that 10.33 meters degree of depth obtain, just be enough to promote in first horizontal pressure force pipeline 6, water liquid weight and water turbine 77 blades are managed the resistance resistance jointly.
The water liquid weight vertical pressure of above-mentioned first to fourth water liquid compression weight storage tank 81～84; Add the atmospheric pressure that pipeline depth of living in has; The potential energy that is respectively 2atm, 3atm, 4atm, 5atm is exerted pressure; And first to the 5th horizontal pressure force pipeline, 6,64,65,66,67 interior water liquid weight and water turbine 77 blades that promote the same terms are managed when hindering resistance jointly; All only need the atmospheric pressure of 1atm, with water liquid weight vertical pressure in the water storage tank of equivalent, thereby the total pressure pipeline will have the unnecessary atmospheric pressure of 1atm+2atm+3atm+4atm=10atm.
Again, the atmospheric pressure that this 10atm is unnecessary can be used to promote again, has etc. in the horizontal pressure force pipeline of water gaging liquid compression weight storage tank; 10 times water liquid weight and 10 water turbine 77 vane group, the also natural different levels horizontal pressure force pipeline 6,64 that can apply pressure to respectively promotes this multi-level interior water liquid weight; With water turbine 77 vane group, and drive generator for electricity generation, and utilize water liquid discharging impulse water turbine (figure does not show) in pipe end; After driving generator for electricity generation, last water flow is gone into the downstream, rivers and creeks.
