Question

На какую предельную высоту можно поднять воду поршневым насосом

Answer 1

При всасывании сверху можно поднять максимум на такую высоту, которая соответствует атмосферному давлению: p*g*h = 1013 гПа (p - плотность воды (1000кг/кубических метров), g - ускорение свободного падения(9.8 Н/кг), h - высота, 1013 гПа - атм. давление), откуда h = около 10,3 м. При "подталкивании" снизу можно поднять на любую высоту.

Answer 2

Maximum Height for Lifting Water with a Piston Pump

The maximum height to which water can be lifted using a piston pump depends on various factors such as atmospheric pressure, pump efficiency, and the density of the fluid being pumped. The maximum height can be calculated using the following formula:

Maximum Height (h) = (Pump Efficiency) * (Atmospheric Pressure) / (Density of Water * g)

Where: - Pump Efficiency is the efficiency of the piston pump. - Atmospheric Pressure is the pressure exerted by the atmosphere at a given point. - Density of Water is the density of water. - g is the acceleration due to gravity.

The maximum height can be affected by the specific design and efficiency of the piston pump being used.

According to the provided search snippets: - Source mentions a formula for calculating the maximum height to which water can be lifted using a piston pump. - Source discusses factors such as atmospheric pressure, pump efficiency, and the density of the fluid being pumped. - Source provides information about the efficiency of the piston pump. - Source mentions the density of water and its impact on the maximum height. - Source discusses the influence of atmospheric pressure and the density of water on the maximum height.

Based on the available information, the maximum height to which water can be lifted with a piston pump can be calculated using the formula mentioned above, taking into account the specific parameters and conditions of the piston pump and the environment in which it operates.
