An asphalt producer proposes an asphalt with the following properties for this rest area: o Maximum specific gravity of the asphalt mixture: 2.535 o Bulk specific gravity of the asphalt mixture at Ndes: 2.46 o Bulk specific gravity of the asphalt mixture at Nmax: 2.49 o Bulk specific gravity of the aggregate blend: 2.68 o Effective specific gravity of the aggregate blend: 2.71 o Apparent specific gravity of the aggregate blend: 2.75 o Maximum aggregate size of the aggregate blend: 19.0 mm o Nominal maximum aggregate size of the aggregate blend: 12.5 mm o Specific gravity of the binder: 1.03 o Mass percentage solids: 94% o Mass percentage dust (< #200) in the aggregates: 10.0% Is this asphalt in agreement with Superpave MoDOT specs for the volume of air, the voids in the mineral aggregates, the voids filled with asphalt and the dust-to-binder ratio? Do you expect any performance problems?

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?
