A pipe with insulation: For the same thickness and type of insulation, the thermal resistance of the insulation 1. Decreases with decreasing radius of the pipe
2. Increases with decreasing radius of the pipe
3. Does not change with decreasing radius of the pipe
4. Could either increase or decrease with decreasing radius of the pipe

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
