Draw a simple circuit for the function y(a, b,c) = a’ + bc. use only the basic logic gates (and, or, and not). now convert your circuit to an equivalent circuit that uses only nand gates. show all your steps, using multiple intermediate circuit diagrams. explain simply what you did for each step. finally, write the sequence of boolean expressions for each step in your transformation until you reach the final equation.

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
