Question

В два сосуда, между которыми находится кран (он закрыт), налита вода. Укажи, в каком сосуде давление воды на дно больше и на сколько, если h1=37 см, а h2=9 см. (Принять g=9.8Н/кг). Ответ (округли до десятых): давление воды на дно больше в (запиши: «левом» или «правом» )..... сосуде на ...... кПа.

Answer 1

Δp=ρ*g*Δh
Δp=1000*9,8*(0,37-0,09)=176,4 Па
Ответ: в левом сосуде на 176,4 Па

Answer 2

Calculating Water Pressure in Two Containers

To calculate the water pressure at the bottom of the two containers, we can use the formula:

P = ρgh

Where: - P is the pressure - ρ is the density of the fluid - g is the acceleration due to gravity - h is the height of the fluid column

Given: - h1 = 37 cm - h2 = 9 cm - g = 9.8 m/s^2

Calculating Pressure in the First Container (h1 = 37 cm)

First, let's calculate the pressure at the bottom of the first container using the given values.

The pressure can be calculated using the formula P = ρgh. Since the density of water is approximately 1000 kg/m^3, we can use this value for ρ.

P1 = (1000 kg/m^3) * (9.8 m/s^2) * (0.37 m)

P1 ≈ 3626.0 Pa

Calculating Pressure in the Second Container (h2 = 9 cm)

Now, let's calculate the pressure at the bottom of the second container using the given values.

P2 = (1000 kg/m^3) * (9.8 m/s^2) * (0.09 m)

P2 ≈ 88.2 Pa

Comparing the Pressures

So, the pressure at the bottom of the first container is approximately 3626.0 Pa, while the pressure at the bottom of the second container is approximately 88.2 Pa.

Therefore, the pressure of water at the bottom is greater in the left container by approximately 3537.8 Pa.
