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.

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
