(a) Variation in the droplet drying time with $\Psi$ at different values of the initial contact angle, θ₀. The rest of the parameters are initial volume, V₀ = 10 nL, T = 30 °C, and RH = 50%. (b) The variation of the normalized mass evaporation rate with the initial mass evaporation rate, $\dot{m}/{\dot{m}}_0$ vs $\Psi$. The rest of the parameters are $T={30}^{°}$C, RH = 50% and ${\theta }_0={50}^{°}$. Reproduced with permission from S. Balusamy, S. Banerjee, and K. C.
