a) If a (300 + Class ID) km transmission line operating at 50 Hz. Determine the rise in voltage at the receiving of transmission line. b) A long transmission line is not loaded? What will be the voltage at receiving end compared to the sending end voltage? Give reasons.

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
