What is the result of entering the command a = min(matA,[],1); for matA given below? If your answer is a row vector, use square brackets to enclose the numbers and commas to separate each value. If your answer is a column vector, use square brackets to enclose the numbers and semicolons to separate each value. If your answer is a single value, simply enter the number

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?
