Q/ A composite wall is formed of a 2.5-cm copper plate (k = 386 W/m.°C), a 3.2-mm layer of 0.038 W/m.°C). The wall is asbestos (k = 0.16 W/m.°C), and a 5-cm layer of fiberglass (k subjected to an overall temperature difference of 560-C. Calculate the heat flow per unit area 1. Water flows at the rate of 0.5 kg/s in a 2.5-cm-diameter tube having a length of 3 m.A constant heat flux is imposed at the tube wall so that the tube wall temperature is40•C higher than the water temperature. Calculate the heat transfer and estimate thetemperature rise in the water. The water is pressurized so that boiling cannot occur.

You are designing a new eco-friendly thermal coffee mug. It is shaped like a small globe to minimize surface area, which is only about 0.04m^2. You use two 0.003m layers of recyclable PETE which has a thermal conductivity, k, of 0.2W/mK around a 0.01m layer of dead air, with a thermal conductivity of 0.026W/mK. Since this is for hot coffee, use a temperature difference of 40K. Q = Ax (T2-T1) / (R1 + R2 + etc) R =x/k. What is the heat lose through the surface in watts?
