Q6: Derive an expression for the capillary height change h for a fluid of surface tension σ and contact angle between two vertical parallel plates a distance W apart, as shown in Figure H.2. What will be for water at 20°C if W = 0.5 mm? For water at 20°C, σ = 0.0728 N/m, y = 9790 N/m², and 0=0°, find the value of h. h = 3 mm. Answer: h= 20 cos 8 W Figure: H.2
