Imagine a small town council consisting of three council members, each member of this council votes on various issues by toggling a small switch at their seat to yes or no position. Assume the yes position produces a logical 1, and no position produces a logical 0. A circuit must be designed that produces a logic 1 output any time two or more of the council members vote yes.
a. Using A, B, and C as the states of each switch, complete a truth table that shows all the possible switch setting and the desired output for each setting.
b. From the truth table in Part a, determine the Boolean expression for the "majority- detector" function.
c. Reduce the function (by using a Karnaugh map), and implement the function directly using gates.

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?
