Determine the density of honey in a glass if the height of the poured honey is 20 cm

Determine the density of honey in a glass if the height of the poured honey is 20 cm, and the pressure on the bottom of the glass is 3 kPa.

Given: h (height of honey poured into a glass) = 20 cm (0.2 m); P (the pressure that honey creates at the bottom of the glass) = 3 kPa (3 * 10 ^ 3 Pa).
Reference values: g (acceleration due to gravity) = 9.81 m / s2 ≈ 10 m / s2.
The sought density of honey is determined by the formula for calculating the hydrostatic pressure of various liquids: P = ρm * g * h, whence ρm = P / (g * h).
Calculation: ρm = 3 * 10 ^ 3 / (10 * 0.2) = 1500 kg / m3.
Answer: The estimated density of honey in a glass is 1500 kg / m3.
