A 100mm diameter steam pipe is covered by two layers of lagging. the insude layer is 40mm thick with K=0.07w/mk, the outside layer is 25mm thick with k=0.1w/mk. the pipe convey steam at a pressure of 1.7MN/m with 30k superheat. the outside temperature of the lagging is 24°C, if the steam pipe is 20m long, determine the heat loss per hour and the interface temperature of the lagging. neglect the temperature drop accross the steam pipe.
