Subject: drawdown gen. Дорогие коллеги.
Помогите уточнить термин drawdown из описания насосов:The static water level is defined as the depth to water when no water is being pumped from the well.
As soon as the pump starts pumping, the water level will start to go down.
The water level will continue to go down until equilibrium is reached, and that is when the friction loss in the aquifer and the casing screen (meter of friction) is the same as the drawdown (meter of head). Падение уровня воды? Спасибо.
