Question

Какое давление должен создавать насос,чтобы поднимать воду на высоту 31м?p=1000кг/м3,g~10Н/кг.Ответ:насос должен создавать давление,равное ?Па

Answer 1

Р=рgh=1000*10*31=310000 Па=310 кПа

Answer 2

Calculating Pressure Required to Lift Water 31m

To calculate the pressure required to lift water to a certain height, we can use the formula: P = ρgh, where: - P is the pressure, - ρ is the density of the fluid (in this case, water, with a density of 1000 kg/m³), - g is the acceleration due to gravity (approximately 10 m/s²), and - h is the height the water needs to be lifted (31m).

Using this formula, we can calculate the pressure required.

Calculation

Using the formula P = ρgh, where: - ρ = 1000 kg/m³ (density of water), - g = 10 m/s² (acceleration due to gravity), and - h = 31m (height to lift the water),

We can calculate the pressure as follows: P = (1000 kg/m³) * (10 m/s²) * (31m) = 310,000 Pa.

Therefore, the pump needs to create a pressure of 310,000 Pa to lift the water to a height of 31m
