Q1 direct mapped cache i 30 points suppose we have 16 bit byte-addresses and the clock frequency is 2ghz. we have the cache parameters as follows: cache size: 4kib block size: 1 word (4 bytes) cache hit time: 2 cycles cache miss penalty: 100 cycles direct mapped cache now suppose we access the following addresses, in order: 0x, 0x0004, 0x0008, 0x000c, 0x1000, 0x1004, 0x1008, 0x100c, 0x, 0x0004, 0x0008, 0x000c q1.1

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?
