| Determine the height of the milk can if it is known that the pressure of the milk at the bottom of the can is 5 kPa, and the density of the milk is 1029 kg / m³.
Given: P (pressure that milk creates at the bottom of the can) = 5 kPa (5 * 10 ^ 3 Pa).
Constants: g (acceleration of gravity) = 9.81 m / s2; by condition we take ρm (milk density) = 1029 kg / m3.
We express and calculate the desired height of the can from the formula: P = ρm * g * h and h = P / (ρm * g).
Let’s make a calculation: h = 5 * 10 ^ 3 / (1029 * 9.81) = 0.495 m (49.5 cm).
Answer: The desired height of the can is 49.5 centimeters
