Suppose that gas at -30°C is stored inside a 1-cm-radius spherical container (k = 50 W/m. K) with a wall thickness of 2 cm. Inside and outside convective heat transfer coefficients are 1250 and 25 W/m2.K. If the ambient temperature is 25°C, a. Calculate overall heat transfer coefficient for the inner area (Ui). Determine heat transfer
rate using Ui.
b. Repeat part a for overall heat transfer coefficient for the outer area (Uo).
