Chapter 1 Basics of Heat Transfer 1-89 A 4-m diameter spherical tank filled with liquid oxygen at 1 atm and -183 ° C is exposed to convection with ambient air. The rate of evaporation of liquid oxygen in the tank as a result of the heat transfer from the ambient air is to be determined. Assumptions 1 Steady operating conditions exist. 2 Heat transfer by radiation is disregarded. 3 The convection heat transfer coefficient is constant and uniform over the surface. 4 The temperature of the thin- shelled spherical tank is nearly equal to the temperature of the oxygen inside.
