Question

В стакан налиты две несмешивающиеся жидкости – вода и сверху бензин. Высота каждого слоя – 4 см. Найти давление жидкостей на дно сосуда. Таблица плотностей ( кг/м3 ) Вода – 1000 Бензин – 710

Answer 1

P=p*g*h=g(h1*p1+h2*p2)=10*0.04*(1000+710)=684Н/м^2

Надеюсь помог.

Answer 2

Calculating Pressure at the Bottom of the Vessel

To calculate the pressure at the bottom of the vessel, we can use the formula for the pressure at a certain depth in a liquid:

p = ρgh

Where: - p = pressure - ρ = density of the liquid - g = acceleration due to gravity - h = height of the liquid column

Given: - Density of water (ρ_water) = 1000 kg/m³ - Density of gasoline (ρ_gasoline) = 710 kg/m³ - Height of each layer (h) = 4 cm = 0.04 m

First, we need to calculate the pressure at the bottom of each layer separately using the formula p = ρgh.

For water: p_water = 1000 kg/m³ * 9.81 m/s² * 0.04 m.

For gasoline: p_gasoline = 710 kg/m³ * 9.81 m/s² * 0.04 m.

Now, we can calculate the total pressure at the bottom of the vessel by adding the pressures due to water and gasoline.

Total Pressure at the Bottom of the Vessel

The total pressure at the bottom of the vessel is the sum of the pressures due to water and gasoline:

p_total = p_water + p_gasoline.

After calculating the individual pressures and adding them together, we can find the total pressure at the bottom of the vessel.
