Question

Определите давление керосина на дно цистерны Если уровень керосина в цистерне 2 метра плотность керосина 800 кг/м3

Answer 1

По формуле давления(p=  ро*g*h). Так как у нас нету площади и силы, то пользуемся этой формулой.P=800*10*2=16000 Па=16 кПа.
Ответ:16 кПа

Answer 2

Calculation of Pressure

To determine the pressure of the kerosene at the bottom of the tank, we can use the formula:

Pressure (P) = density (ρ) * gravitational acceleration (g) * height (h)

Given that the level of kerosene in the tank is 2 meters and the density of kerosene is 800 kg/m³, we can substitute these values into the formula.

Height (h) = 2 meters Density (ρ) = 800 kg/m³

Using the value of gravitational acceleration, which is approximately 9.81 m/s², we can calculate the pressure:

Pressure (P) = 800 kg/m³ * 9.81 m/s² * 2 meters

Calculating this expression, we find that the pressure of the kerosene at the bottom of the tank is 15,696 Pascal (Pa) or 15.7 kilopascals (kPa).

Therefore, the pressure of the kerosene at the bottom of the tank is approximately 15.7 kPa.
