Question

Problem 3: Consider a 50 micron droplet of hexane ($C_6H_{14}$) injected into a hot laminar air stream with a gas velocity of $U_g = 0.1$ m/s at $T_g = 1000K$. Assuming the fuel droplet is at its boiling point and begins to vaporize immediately, determine the vaporization length of the droplet from its injection point in the gas flow. Hexane data: $h_{fg} = 365.3$ kJ/kg, $\rho = 664$ kg/m$^3$, $T_b = 341.7$ K at atmospheric pressure. Assume droplet surface temperature is same as the boiling point (normally this temperature needs to be calculated using the relationship between surface temperature, vapor mass fraction just above the surface of the droplet and the Clausius-Clapeyron equation)
