Q2- Water flows inside a steel pipe with an ID of 2.5 cm. The wall thickness is 2 mm. and the convection coefficient on the inside is 100 Wm² C. The convection coefficient on the outside is 10 W/m C. The pipe is covered with a layer of asbestos, 1-determine the thickness of the asbestos layer at the critical insulation radius of the pipe. 2-calculate the change percent of heat transfer with and without the insulation. 3-commet on your results,
