Answer :
Final Answer:
The diameter of the capillary tube is 0.15 mm.
Explanation:
The height to which water rises in a capillary tube is given by the following equation:
h = 2σ cos θ / ρ g d
where:
h is the height of the water column (cm)
σ is the surface tension of water (N/m)
θ is the contact angle between water and the glass (°)
ρ is the density of water (kg/m³)
g is the acceleration due to gravity (m/s²)
d is the diameter of the capillary tube (m)
We are given that h = 17 cm, σ = 0.0728 N/m, θ = 0°, ρ = 1000 kg/m³, and g = 9.81 m/s².
Substituting these values into the equation, we get:
17 = 2 × 0.0728 × cos(0°) / 1000 × 9.81 × d
d = 0.15 mm
Therefore, the diameter of the capillary tube is 0.15 mm.
