(a) Describe heat engine. How is this engine characterized?
(b) Describe Perpetual motion machines of first kind and second kind, i.e. PMM1 and PMM2. Are such machines possible to build? If no then why?
(c) A reversible engine receives heat from a high temperature reservoir at T1K and rejects heat to a low temperature sink at 560 oC. A second reversible engine receives heat rejected by the first engine at 560 oC and rejects heat to cold reservoir at 4.4 oC. Determine the temperature T1 for the engines , if they deliver same work.
