Question

В цилиндрический сосуд высотой 80 см налиты нефть и керосин. Определите давление, которое оказывают жидкости на дно сосуда, если их объемы равны.

Answer 1

Ответ:

6272Па

Объяснение:

80см - это 0.8м

плотность нефти - 800 кг на метр в кубе

плотность керосина - 800 кг на метр в кубе

давление = плотность * h * g

давление = 800*0.8*9.8=6272Па

Answer 2

Calculation of Pressure Exerted by Oil and Kerosene in the Cylinder

To determine the pressure exerted by the oil and kerosene on the bottom of the cylindrical vessel, we need to consider the height and volume of the liquids.

Given: - Height of the cylindrical vessel = 80 cm - Volume of oil = Volume of kerosene

To calculate the pressure, we can use the formula:

Pressure = Force / Area

In this case, the force is the weight of the liquids, and the area is the bottom surface area of the vessel.

To find the weight of the liquids, we can use the formula:

Weight = Mass x Gravity

The mass of the liquids can be calculated using the formula:

Mass = Density x Volume

Since the volume of oil and kerosene is equal, we can calculate the mass of one of the liquids and then double it to account for both liquids.

The density of oil and kerosene may vary, so we need to assume a specific value. Let's assume the density of both liquids is 0.8 g/cm³.

Now let's calculate the pressure exerted by the liquids on the bottom of the vessel.

Calculation Steps:

1. Calculate the mass of one of the liquids: - Mass = Density x Volume - Volume = Height x Area of the base - Area of the base = π x (radius of the base)²

2. Calculate the weight of one of the liquids: - Weight = Mass x Gravity

3. Calculate the pressure exerted by the liquids: - Pressure = Weight / Area of the base

Calculation:

1. Calculate the mass of one of the liquids: - Volume = 80 cm x π x (radius of the base)² - Since the volume of oil and kerosene is equal, we can use the same formula for both liquids.

2. Calculate the weight of one of the liquids: - Weight = Mass x Gravity - Gravity = 9.8 m/s²

3. Calculate the pressure exerted by the liquids: - Pressure = Weight / Area of the base

Since we don't have the radius of the base of the vessel, we cannot provide an exact numerical answer without this information. However, you can use the provided formulas and assumptions to calculate the pressure yourself.

Please note that the density assumption of 0.8 g/cm³ is just an example, and the actual density of oil and kerosene may vary. Additionally, the accuracy of the calculation depends on the accuracy of the assumptions made.
