Consider a coaxial cable of inner radius a and outer radius b, filled with a lossless dielectric material. The phasor-domain fields inside of the cable (a < rho < b) for a time-harmonic wave traveling down the cable are given in cylindrical coordinates as:
E= rho (1/ rho)e^- jkz
H= φ (1/rho) 1/ ηo√εr. e^-jkz
Calculate the total time-average power (in Watts) flowing in the z direction down the cable.

Areheat rankine cycle operates with water as the working fluid. steam enters the first turbine at 8 mpa and 450°c and exits at 0.8 mpa. it is then reheated to 400°c before entering the second turbine, where it exits at 10 kpa. if the amount of work into the pump is 8.04 kj/kg and the net work per cycle produced is 1410.25 kj/kg, determine the thermal efficiency of the cycle.
