35 cm diameter stainless steel 304 (ρ = 7901 kg / m3 ) cylindrical shaft made from a furnace has been removed. The furnace is at a uniform temperature of 505 oC. The cylindrical shaft then moves to a 145 oC chamber it has been allowed to cool slowly in its environment. Heat transfer coefficient with average convection in the room h = 61.1 W / m2.K . This cylindrical shaft's surface temperature is measured 28 minutes after the start of cooling. Find it with the following methods. a) lumped system method b) approximate analytical method c) chart method
