Ts=108;//Temp of surface of bottom of pan[degree Celcius]
Tsat=100;//Saturation temp of water[degree Celcius]
D=0.3;//Diameter[m]
//Properties of water at the saturation temp
rho_l=957.9;//Density of liquid[kg/m^3]
rho_v=0.6;//Density of vapour[kg/m^3]
Pr_l=1.75;//Prandtl no of liquid
mu_l=0.282*10^(-3);//Viscosity of liquid[kg/m.s]
