Consider a 3 x 3 voq switch that we studied in class. here, there are three input queues at each port, which hold packets bound for the three output ports (a total of nine queues). for example, q13 is the length of the queue (in packets) at input port 1, which are destined for output port 3. suppose that we denote a matching using the notation in which [13 22 31] indi cates that one packet each from the queues q13, q22 and q31 are sent to the output ports 3, 2 and 1 respectively.

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?
