An aggregate blend is composed of 53% coarse aggregate by weight
(sp. gr. 2.702), 43% fine aggregate (sp. gr. 2.621), and 4% filler
(sp. gr. 2.779)/ the compacted specimen contains 6% asphalt binder
(sp. gr. 1.052) by weight of total mix, and has a bulk density of
145.2 lb/ft3. ignoring
absorption, computer the percent voids in total mix, percent voids
in mineral aggregate, and the percent voids filled with asphalt.

Avolume of 2.65 m3 of air in a rigid, insulated container fitted with a paddle wheel is initially at 264 k, 5.6 bar. the air receives 432 kj by work from the paddle wheel. assuming the ideal gas model with cv = 0.71 kj/kg • k, determine for the air the amount of entropy produced, in kj/k

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
