Question

В сосуд высотой 30 см налита вода уровень которой ниже края сосуда на 4 см.чему равно давление воды на дно сосуда? Чему равно сила давления воды на дно сосуда если площадь дна 0,002м2. Плотность воды 1000 кг/м3

Answer 1

P=ro*g*(h-L)=1000*10*0,26 Па = 2600 Па
F=S*p=2600*0,002 Н = 5,2 Н

Answer 2

P=Pgh
p=1000*10*0.26=2600 Па
F=pS
F=2600*0.002=5.2H

Answer 3

Calculation of Water Pressure at the Bottom of the Vessel

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

Pressure = Density × Gravitational Acceleration × Height

Given: - Height of the vessel (h) = 30 cm = 0.3 m - Water level below the rim of the vessel (h') = 4 cm = 0.04 m - Density of water (ρ) = 1000 kg/m³

To find the height of the water column above the bottom of the vessel, we subtract the water level below the rim from the total height of the vessel:

Height of water column (hᵢ) = h - h'

Substituting the given values:

hᵢ = 0.3 m - 0.04 m = 0.26 m

Now we can calculate the pressure at the bottom of the vessel using the formula mentioned earlier:

Pressure = ρ × g × hᵢ

Substituting the values:

Pressure = 1000 kg/m³ × 9.8 m/s² × 0.26 m

Calculating the result:

Pressure = 2548 Pa

Therefore, the pressure of the water at the bottom of the vessel is 2548 Pascal (Pa).
