Design and draw a simple circuit that has 3 inputs a, b, and c and that produces an output y that has the value 1 whenever two or more of the input variables have the value of 1; otherwise the output value for y should be 0.

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.
