This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A curve in a speed track has a radius of 1200 ft and a rated speed of 120 mi/h. A racing car starts skidding on the curve when traveling at a speed of 180 mi/h. Determine:
a. the banking angle θ
b. the coefficient of static friction between the tires and the track under the prevailing conditions
c. the minimum speed at which the same car could negotiate the curve.

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?
