Anylon pipe has a bore of 50mm and a wall thickness of 5mm. it is covered with insulation 10mm thick. the thermal conductivity of the nylon is 0.25w/mk and for the insulation it is 0.1 w/mk. the inside of the pipe carries hot water at 50°c and the outer surface of the pipe is at 10°c. calculate the heat loss per metre length and the temperature between the two materials.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
