Calculate the heat flux, 25 m from the flame surface in the direction of the wind, from a 10 m pool diameter of n-hexane. The following data are available:

Boiling temperature, Tb : 341.9 K Heat of combustion, Hc : 44700 kJ/kg Heat of vaporization, Hv : 334 kJ/kg Specific heat capacity, Cp : 1.7 kJ/kgK Ambient temperature, Ta : 278 K Soot surface emitting power, SEPsoot : 20 kW/m2 Wind velocity, uw : 5 m/s Density of air, air : 1.21 kg/m3 Liquid density at boiling temperature, L : 616 kg/m3 Viscosity of air, air : 16.7 Pa-s Saturation water vapor pressure, Pwo: 2320 kPa Relative humidity, RH : 0.8 Radiation Fraction, Fs : 0.2 Please use Mundan method and Thomas method for burning rate and flame length calculations, respectively. Consider 20% of the flame surface fraction is not covered by soot. You may assume 49.6 as flame tilt angle towards the receptor. Please list all the steps properly and then try to solve the problem.
