Building alu based 4-bit addition using two 74sl74 (4 d ff's) and a 4-bit adder. provide an implementation to perform the following alu addition operation add a. b- this operation adds a and b and stores the result in a create a 4-bit register using 4 d ffs and it acts as an accumulator. this accumulator is connected with an adder and is performing the following task the initial value of the accumulator is 0 and every time a clock pulse is given, it adds the current value of the accumulator (let's call it a) and a given 4-bit input b. the b input is provided using 4 input switches. thus, the accumulator stores the addition of multiple 4-bit values provided to the alu -draw the circuit/logic diagram.

Steam at a pressure of 100 kpa and a quality of 50% initially fills a rigid vessel having a volume of 0.5 m^3. the steam is then heated, causing the pressure in the vessel to rise to 150 kpa. determine: i. the mass of the steam in the vessel. ii. the temperature and quality of the steam after the heating process. ii the mass of the vapour, mg and liquid, m in the vessel after the heating process. if the steam in the vessel is now further heated, what would the pressure and temperature in the vessel be when all steam has turned into saturated vapour? b. sketch the processes in part (a) and part (b) on p-v and t-v diagrams, indicating clearly the temperatures, pressures and the paths. c.
