Abstract:
The paper defined cavitation characteristics of jet pumps operating on liquids on thermophysical characteristics are not reaching the saturation line. An analytical dependence is obtained for the limiting ejection coefficient $u_*$ on the number of cavitation $\sigma$ in its classical definition. A comparison is made for the experimental values of the limiting ejection coefficient $u_*$ with the calculated dependence of $u_*(\sigma)$. The possibility is shown for determining the number of cavitation $\sigma$, which corresponds to a threshold mode of the jet pump in the sense of parameter of pressure input data in the supply lines.
