Question

Какой высоты слой масла подсолнечного оказывает давление на дно сосуда, равное 5,58 кПа?

Answer 1

Объяснение:

Дано

р=5,58 кПа=5,58×10³ Па

g≈10Н/кг

р=916кг/м³ - плотность подсолнечного масла при 20⁰С

Найти

h=?

Решение

р=p×g×h

h=p/(pg)

h=5,58×10³/(916×10)=0,60917 м = 0,61 м = 61 см.

Ответ: 0,61 м или 61 см

Answer 2

Calculating the Pressure Exerted by a Layer of Sunflower Oil

To calculate the pressure exerted by a layer of sunflower oil on the bottom of a vessel, we can use the formula for pressure:

Pressure (P) = Density (ρ) × Acceleration due to gravity (g) × Height (h)

Given: - Pressure (P) = 5.58 kPa - Density of sunflower oil (ρ) = 920 kg/m³ (approximate value for sunflower oil) - Acceleration due to gravity (g) = 9.81 m/s² (standard value)

We can rearrange the formula to solve for the height (h):

Height (h) = Pressure (P) / (Density (ρ) × Acceleration due to gravity (g))

Calculating the Height of the Sunflower Oil Layer

Using the given values and the formula, we can calculate the height of the sunflower oil layer:

Height (h) = 5.58 kPa / (920 kg/m³ × 9.81 m/s²)

Calculating the height: Height (h) ≈ 0.000605 meters

Therefore, the layer of sunflower oil exerts a pressure of 5.58 kPa at the bottom of the vessel when it is approximately 0.000605 meters in height.
