An array with 150 unique elements is subscripted starting with 0. you would like to iteratively use partition to find the thirty largest values, but there is no requirement that the thirty largest values be ordered. which of the following is not correct?
a. if 119 is returned from partition, we must continue.
b. if 118 is returned from partition, we must continue.
c. if 131 is returned from partition, we must continue.
d. if 120 is returned from partition, we are done.

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?
