Technological connection nodes GGE

The HGE funnel (3) is connected to the lower water supply (siphon) adapter, which is connected to the vertical pipe (siphon) (5), which is connected to the upper water supply (siphon) adapter (6), which is connected to the water turbine (7), which is connected with an electric current generator (8).

The method of operation of gravity-hydraulic power plants (HGE)

The HGE funnel is installed with the lower part of the siphon into the reservoir on the support (2) so that the upper surface of the funnel is submerged by the value Δ = 5 ÷ 10 cm min.

The funnel is a cone round straight truncated volume

$$W=\frac{\pi }{3}h(R^2+r^2+Rr)\begin{array}{cc}(m^3);& \end{array}$$

G = γW is the weight of water in the volume of the funnel;

"Δ" - the larger, the greater G "by value;

[R(R+r) - 2r²]cosα(h+∆)-(h+∆)πr²γ=γπ(h+∆) [ $$\frac{1}{3}$$

R(R+r)-2r²]cosα-r²];G ″ = GG ′ = γ $$\frac{\pi }{3}$$

[R (R + r) - 2r ² ] cosα (h + ∆) - (h + ∆) πr ² γ = γπ (h + ∆) [ $$\frac{\mathrm{one}}{3}$$

R (R + r) -2r ² ] cosα-r ² ];

;γ - specific gravity of water $$=1000\frac{\mathrm{to}g}{m^3}$$

;

Round cylinder with straight height h = R (m) and cross-sectional area S _aa = πr ² (a) = W ₁ ;

W ₂ = WW ₁ - the volume of the cone of a circular straight line truncated minus the volume of a circular straight cylinder

G ′ = γW ₁ h = γπr ² h (kg); G ″ = GG ′.

G ′ - the weight of a round straight cylinder with a height h statically balances the water level in the siphon “h”.

(кг) уравновешивает уровень воды в сифоне ΔН. $$G^{″}=\left[\frac{\pi }{3}h\left(R^2+r^2+Rr\right)-\pi r^{2}h\right]\gamma$$

(kg) balances the water level in the siphon ΔН.

. $$G^{″}=\gamma \pi h\left[\frac{R(R+r)-2r^2}{3}\right]$$

.

;According to the law of Jacob Bernoulli $$\Delta H=\frac{P}{\gamma }$$

;

Section pressure S _{a′-a ′} = G ″ cos ² α; πr ² h;

$$\Delta H=\frac{\gamma \pi h[R(R+r)-2r^2]{\cos }^2\alpha }{3\gamma \pi r^2}=\frac{R[R(R+r)-2r^2]}{3r^2}{\cos }^2\alpha ;\begin{array}{cc}& \Delta h=\Delta H{\eta }_h.\end{array}$$

η _h - hydraulic efficiency = 0.8.

Numeric example:

R = 3 m; r = 1 m; η _h = 0,8cos ² α = 0,499

$$\Delta H=\frac{3[3(3+\mathrm{one})-2\times {\mathrm{one}}^2]{\cos }^2\alpha }{3\times {\mathrm{one}}^2}=10\times 0.499=4.99m;\begin{array}{cc}& \Delta h=4.99\times 0.8=3.99m.\end{array}$$
