Question

2. Давление, которое оказывает керосин на дно бака, равно 1,6 кПа. Определитевысоту слоя керосина в баке һ. Плотность керосина p= 800к. Коэффициент у принять равным 10 H КГ M 13 КГ​

Answer 1

Ответ:

Объяснение:

Дано:

p = 1,6 кПа = 1 600 Па

ρ = 800 кг/м³

g = 10 Н/кг

____________

h - ?

Давление:

p = ρ·g·h

Высота слоя керосина:

h = p / (ρ·g)

h = 1 600 / (800·10) = 0,20 м     или  h = 20 см

Answer 2

Based on the information provided, we can calculate the height of the kerosene layer in the tank. The pressure exerted by the kerosene on the bottom of the tank is given as 1.6 kPa, and the density of kerosene is given as 800 kg/m^3. We can use the formula for pressure in a fluid to calculate the height of the kerosene layer.

Formula for Pressure in a Fluid:

The pressure exerted by a fluid at a certain depth is given by the formula:

P = ρgh

Where: P is the pressure exerted by the fluid, ρ is the density of the fluid, g is the acceleration due to gravity, and h is the height or depth of the fluid.

Calculation:

In this case, we are given the pressure (P) as 1.6 kPa, the density (ρ) as 800 kg/m^3, and the acceleration due to gravity (g) as 10 m/s^2.

Converting the pressure from kPa to Pa, we have: P = 1.6 kPa = 1.6 * 10^3 Pa

Substituting the given values into the formula, we can solve for h: 1.6 * 10^3 Pa = 800 kg/m^3 * 10 m/s^2 * h

Simplifying the equation, we find: h = (1.6 * 10^3 Pa) / (800 kg/m^3 * 10 m/s^2)

Calculating the value, we get: h = 0.2 m

Therefore, the height of the kerosene layer in the tank is 0.2 meters.

Please note that the given values for the density of kerosene and the coefficient "у" are not used in the calculation.
