-A container has a vertical tube,whose inner radius is 12.00 mm,connected to it at its side.An unknown liquid reaches level A in the container and level B in the tube-level A being 5.0 cm higher than level B.The liquid supports a 20.0 cm high column of oil,between levels B and C,whose density is 320 kg/m³.In the figure,the gauge pressure at level B is closest to:

Question

Quizplus · Accepted Answer

The gauge pressure at level B is due to the height difference between levels A and B and the column of oil. The pressure due to the liquid is ρgh, where ρ is the density of the liquid, g is the acceleration due to gravity, and h is the height difference. The pressure due to the oil column is ρ_oil * g * h_oil. The total gauge pressure is the sum of these pressures. Given the density of the oil and the height of the column, the pressure at level B is closest to 630 Pa.
