Astraight fin is made from an aluminum alloy (k = 160 w/m-k) and is 0.5 cm in diameter and 30 cm long. the temperature at the base of the fin is 75oc and it is exposed to flowing air at 20oc with h = 20 w/m2-k. that is the rate of heat transfer from this pin?

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
