Design a minimum two-level nor-nor circuit to realize f(w, x, y, z) = ∑m(10, 12, 14). enter the boolean equation that describes the circuit. then convert the circuit to two-level nand-and circuit. do not use gate symbols with bubbles in your final answer. enter the boolean equation that describes the circuit. also attach any karnaugh maps used to derive the equations for the circuit.

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.
