Find a minimum two-level, multiple-output AND-ORgate circuit to realize thesefunctions (eight gates minimum).f1(a, b, c, d) = Σm(10, 11, 12, 15) + Σd(4, 8, 14)f2(a, b, c, d) = Σm(0, 4, 8, 9) + Σd(1, 10, 12)f3(a, b, c, d) = Σm(4, 11, 13, 14, 15) + Σd(5, 9, 12)

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
