Question: the boiling temperature of oxygen at atmospheric pressure at sea...

Question details

The boiling temperature of oxygen at atmospheric pressure at sea level 1 atm pressure) is -183C. Therefore, oxygen is commonly used in low-tempereture scientific studies since the temperature of liquid oxygen in a tank open to the atmosphere will remain constant at -183C until it is depleted. Any heat transfer to the tank will result in the evaporation of some liquid oxygen, which has a heat of vaporization of 213 kJ/kg and a density of 140 kg/m3 at 1atm. Consider a 24-m-diameter spherical tank that is initially filled with liquid oxygen at 1 etm and -183-C. The tank is exposed to amblent air at 15 C, with a combined convection and rediation heat transfer coefficient of 35 W/m2K. The temperature of the thin-shelled sphericel tenk is observed to be almost the same as the temperature of the oxygen inside Oz vapor a 15C 1 atm Liquid O2 -183C Insulation value Required information 10.00 points You did not recelve full credit for this question in a previous attempt Determine the rate of evaporation in kg/s) of the iquid oxygen in the tank as a result of the heet transfer from the ambient air if the tank is not insulated
