The system shown in the figure below is used to estimate the pressure inside the tank by measuring the height of the liquid in the 1 mm diameter tube. The fluid is at 60°C. What will be the capillary rise if the fluid is water [surface tension (σ) = 0.0662 N/m, density (ρ) = 983 kg/m3, angle of contact (θ) = 0°] and if the fluid is mercury [surface tension (σ) = 0.47 N/m, density (ρ)= 13500 kg/m3, angle of contact (θ) = 130°].
1
Capillary rise in case of water = 0.0275 m
2
Capillary rise in case of mercury = -0.0091 m
3
Capillary rise in case of water = 0.0137 m
4
Capillary rise in case of mercury = -0.00456 m
