The bottom area of the cylindrical can is S = 2.0 dm 2. It is poured with machine oil with a volume of V = 5.0.

The bottom area of the cylindrical can is S = 2.0 dm 2. It is poured with machine oil with a volume of V = 5.0. Determine the height of the oil layer in the jar and its mass.

Initial data: S (bottom area of a cylindrical can) = 2 dm2 (2 * 10-2 m2); V (volume of machine oil poured into the can) = 5 dm3 (5 * 10-3 m3).

Reference data: ρ (density of engine oil) = 900 kg / m3.

1) Determine the height of the engine oil layer in the can: V = S * h and h = V / S = 5 * 10-3 / (2 * 10-2) = 0.25 m (25 cm).

2) Calculate the mass of the poured machine oil: m = ρ * V = 900 * 5 * 10-3 = 4.5 kg.

Answer: 4.5 kg of machine oil was poured into the jar, the layer height of which is 25 seconds.
