Question

Давления керосина в сосуде 500 Па. Как изменится давление если в место керосина налить такой же объем воды? Плотность воды 1000 кг/м3 керосина 800кг/м3

Answer 1

Ответ
H=P/GP=500/10*800=0.06m
P=10*1000*0.06=600Па

Answer 2

Calculation of Pressure Change

To calculate the change in pressure when the same volume of water is poured into the vessel instead of kerosene, we can use the principle of Pascal's law, which states that the pressure in a fluid is transmitted equally in all directions.

Given: - Initial pressure of kerosene in the vessel: 500 Pa - Density of water: 1000 kg/m³ - Density of kerosene: 800 kg/m³

To find the change in pressure, we can use the equation:

Change in pressure = (density of water - density of kerosene) * initial pressure of kerosene.

Substituting the given values into the equation, we get:

Change in pressure = (1000 kg/m³ - 800 kg/m³) * 500 Pa

Simplifying the equation:

Change in pressure = 200 kg/m³ * 500 Pa

Calculating the product:

Change in pressure = 100,000 Pa

Therefore, if the same volume of water is poured into the vessel instead of kerosene, the pressure will increase by 100,000 Pa.

Please note that the above calculation assumes that the volume of the vessel remains constant and that there are no other factors affecting the pressure change.
