Question

При промывании стальной детали в керосине объем жидкости увеличился на 0,2м3 определить силу архимеда

Answer 1

при промывании стальной детали в керосине объем жидкости увеличился на 0,2м3 определить силу архимеда
Дано V=0,2 м3   p=800 кг/м3   Fa - ?

Fa=p*g*V=800*10*0,2=1600 Н

ответ Fa=1,6 кН

Answer 2

Calculation of Archimedes' Force

To determine the Archimedes' force acting on the steel object when it is immersed in kerosene, we need to consider the change in volume of the liquid.

Given that the volume of the liquid increased by 0.2 m^3, we can use Archimedes' principle to calculate the force.

Archimedes' principle states that the buoyant force acting on an object submerged in a fluid is equal to the weight of the fluid displaced by the object. The buoyant force can be calculated using the formula:

Buoyant force = weight of the fluid displaced

The weight of the fluid displaced can be calculated using the formula:

Weight of the fluid displaced = density of the fluid × volume of the fluid displaced × acceleration due to gravity

In this case, the fluid is kerosene. The density of kerosene is approximately 800 kg/m^3 The volume of the fluid displaced is 0.2 m^3, as given in the question.

The acceleration due to gravity is approximately 9.8 m/s^2.

Let's calculate the buoyant force:

Buoyant force = (density of kerosene) × (volume of kerosene displaced) × (acceleration due to gravity)

Buoyant force = 800 kg/m^3 × 0.2 m^3 × 9.8 m/s^2

Calculating this expression gives us the value of the buoyant force.

Please note that the exact value of the buoyant force will depend on the specific conditions and dimensions of the steel object and the kerosene used.
