Question

На какой глубине давление в водоеме с учётом атмосферного давления равно 180180 кПакПа?

Answer 1

Ответ: 18 м

Объяснение:

р=ρ g h , h=p/ρg,

h=180000Па/ 1000кг/м³ *9,8 Н/кг=18 м

Answer 2

Water Pressure at a Depth Considering Atmospheric Pressure

To calculate the depth at which the water pressure, taking into account atmospheric pressure, is equal to 180 kPa, we can use the formula:

Pressure = Density × Gravity × Depth + Atmospheric Pressure

Where: - Pressure is the total pressure at a certain depth - Density is the density of the fluid (in this case, water) - Gravity is the acceleration due to gravity - Depth is the depth of the water - Atmospheric Pressure is the pressure exerted by the atmosphere at the surface

Calculation

Using the given atmospheric pressure of 101.3 kPa and the density of water as 1000 kg/m³, we can rearrange the formula to solve for the depth:

Depth = (Pressure - Atmospheric Pressure) / (Density × Gravity)

Substituting the values: Depth = (180 kPa - 101.3 kPa) / (1000 kg/m³ × 9.81 m/s²)

Calculating this gives us: Depth ≈ 7.8 meters

Therefore, the depth at which the water pressure, taking into account atmospheric pressure, is equal to 180 kPa is approximately 7.8 meters.
