A vehicle is to be parked over night in the open away from large surrounding objects. It is desired to know if dew or frost may form on the vehicle top. Asume the convection coefficient h from ambient air to vehicle top is 6.0 W/m^2 (Celsius) Equivalent sky temperature is -18 degree celsius Emissivity of vehicle top is .84. Convection is negliable. Determine the temperature of the vehicle top when the air temperature is 5 degree celsius. State which formation dew or frost occurs.
