Question

Фитиль опустили в керосиновую лампу так, что его нижний конец оказался на дне. высота резервуара для керосина 10 см , определить давление на нижний конец фитиля

Answer 1

Po=800 кг/м3    h=0.1 м    p=?
====
p=po*g*h=800*10*0.1=800 Па

Answer 2

Calculation of Pressure on the Bottom End of the Wick in a Kerosene Lamp

To determine the pressure on the bottom end of the wick in a kerosene lamp, we need to consider the height of the kerosene reservoir and the properties of the liquid.

Given: - Height of the kerosene reservoir: 10 cm

To calculate the pressure at the bottom end of the wick, we can use the hydrostatic pressure formula:

Pressure = Density x Gravity x Height

In this case, the density of kerosene and the acceleration due to gravity are constant, so we can simplify the formula to:

Pressure = Constant x Height

Since we are only interested in the relative pressure, we can assume the constant to be 1.

Therefore, the pressure at the bottom end of the wick is equal to the height of the kerosene reservoir.

Pressure = 10 cm

Please note that this calculation assumes ideal conditions and does not take into account factors such as the viscosity of the kerosene or any other external influences that may affect the pressure.

I hope this helps! Let me know if you have any further questions.
