Analyze the heat transfer in Flask B and draw
a schematic of energy flows. Derive
the equations to determine the outer surface
temperature Ts,o and the water cooling
rate, dTwater/dt. In this case, the air layer
temperature is assumed to be uniform and constantly below the
inner surface temperature by 20°C. The convection coefficient in
the air layer hi = 10 W/(m2-K).
