Question

В цистерне, заполненной нефтью, на глубене 3 м поставили кран. Определите давление на кран

Answer 1

Дано h=3 м     p=800 кг/м3    P- ?

P= p*g*h=800*10*3=24 кПа

Answer 2

Calculating Pressure in an Oil-Filled Tank

To calculate the pressure at the bottom of the oil-filled tank, we can use the formula for pressure:

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

Where: - Density (ρ): The density of the oil. - Acceleration due to gravity (g): The acceleration due to gravity, which is approximately 9.81 m/s^2. - Height (h): The depth of the oil in the tank.

Using the Given Information

In this case, the tank is filled with oil and the depth of the oil is 3 meters. We can assume the density of the oil to be a standard value for crude oil, which is approximately 850 kg/m^3.

Calculating the Pressure

Using the formula for pressure, we can calculate the pressure at the bottom of the tank:

Pressure (P) = 850 kg/m^3 × 9.81 m/s^2 × 3 m

Calculating the above expression gives us the pressure at the bottom of the tank.

Conclusion

By using the given information and the formula for pressure, we can calculate the pressure at the bottom of the oil-filled tank.
