Calculate the magnitude of capillary effect in millimeters in a glass ...
Explanation: Capillarity rise or fall
h=4*cosθ*σ/ρ*g*d
=4*cos130*0.51/13600*9.81*0.007
=140 mm.
h=4*cosθ*σ/ρ*g*d
=4*cos130*0.51/13600*9.81*0.007
=140 mm.

Calculate the magnitude of capillary effect in millimeters in a glass ...
°.
The magnitude of capillary effect can be calculated using the formula:
h = (2T cosθ) / (ρgr)
where:
h = height of liquid rise
T = surface tension of liquid
θ = angle of contact
ρ = density of liquid
g = acceleration due to gravity
r = radius of tube
In this problem, we are given:
T = 0.51 N/m
θ = 130°
ρ = 13,534 kg/m³ (density of mercury at 25°C)
g = 9.81 m/s²
r = 7/2 = 3.5 mm
Substituting these values into the formula, we get:
h = (2 × 0.51 × cos130°) / (13,534 × 9.81 × 0.0035)
h = 4.56 mm
Therefore, the magnitude of capillary effect in a glass tube of 7mm diameter, when immersed in mercury, is 4.56 mm.
