Question:

A cryogenic fluid is stored in a 0.3 m diameter spherical container in still air. If the convective heat transfer coefficient between the outer surface of the container and the air is 6.8 W/(m2 K), the temperature of the air is 27?C and the temperature of the surface of the sphere is ??183?C, determine the rate of heat transfer by convection.GIVENA sphere in still airSphere diameter (D) = 0.3 mConvective heat transfer coefficient hc = 6.8 W/(m2 K)Sphere surface temperature (Ts) = ??183?CAmbient air temperature (T??) = 27?CASSUMPTIONSSteady state heatflow
