Figure shows the schematic of a liquid droplet with radius, R and contact angle, θ . Using these two independent parameters, expressions for volume and base area of the liquid droplet can be obtained: fore, expressions for V and A yield a system of non-linear equations, with θ and R as independent variables; θ is obtained after solving these equations. It should be noted that there are more sophisticated methods for determining the contact angles . In this work, we focus on capturing the qualitative trends in variation of contact angle rather that obtaining precise quantitative estimates. Therefore, investigations in such directions are not undertaken.
