If a and b are both int arrays, then a b; will

a. return true if a and b are aliases and return false otherwise

b. create an alias

c. return true if each corresponding element of b is equal to each corresponding element of a (that is, a[0] is equal to b(01, a[1] is equal to b[1] and so forth) and return false otherwise

d. copy all elements of b into a

e. copy the 0h element of b into the 0h element

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?

The higher the astm grain size number, the finer the gran is. a)-true b)-false
