Determine (a) the maximum thermal efficiency of reversible power cycles operating between a hot reservoir at 1000°c and a cold reservoir at 200°c and (b) the maximum cops for reversible refrigeration and heat pump cycies, respectively, between 28°c and 14°c.

Amass-spring-viscous damper system of mass 3 kg has a frequency of 100 rad/s and is critically damped. its initial conditions are x(0)-3 mm and (0)-2.3 m/s. does the system overshoot its equilibrium position? prove your answer

The ivanpah solar thermal power plant cost $2.2 billion to build. the gross plant electric output is 392 mw, and the net output is 377 mw. the planned capacity factor was 27.4%, but the actual capacity factor in 2016 was 20.5%. at best the plant thermal efficiency appears to be 18%. in addition, for the daily startup process, the solar plant also burned 1.3x10^12 btu of natural gas in 2016. the cost of natural gas in 2016 was about $2.5 per million btu. assuming a levelized annual fixed charge rate of 7%, determine (a) the capital cost (c/kwh) and (b) the fuel cost (e/k wh) for the electricity in 2016.
