Question

Сколько метров подсолнечного масла нужно налить в цилиндрический сосуд площадью дна 100 м²,чтобы создать давление на дно сосуда в 1,6 кПа?

Answer 1

 p0=100 см^2=0,01 м^2P=1,6 кПА=1600 паg=10h-? p=ро*g*h,h=p/(ро*g)=1600/0,01*10=1600/0.1=16000 м

Answer 2

Calculation of the Required Volume of Sunflower Oil

To calculate the volume of sunflower oil needed to create a pressure of 1.6 kPa on the bottom of a cylindrical vessel with a base area of 100 m², we can use the formula for pressure:

Pressure (P) = Force (F) / Area (A)

In this case, the force exerted by the sunflower oil on the bottom of the vessel is equal to the weight of the oil. The weight of an object can be calculated using the formula:

Weight (W) = Mass (m) x Gravitational Acceleration (g)

The mass of the sunflower oil can be calculated using the formula:

Mass (m) = Density (ρ) x Volume (V)

Combining these formulas, we can calculate the volume of sunflower oil needed:

Volume (V) = (Pressure (P) x Area (A)) / (Density (ρ) x Gravitational Acceleration (g))

Now, let's substitute the given values into the formula:

Pressure (P) = 1.6 kPa = 1.6 x 10³ Pa Area (A) = 100 m² Density (ρ) of sunflower oil =Gravitational Acceleration (g) = Using the given values, we can calculate the volume of sunflower oil needed.
