A mixture that is 15 percent carbon dioxide, 5 percent carbon monoxide, 10 percent oxygen, and 70 percent nitrogen by volume undergoes an adiabatic compression process having a compression ratio of 81. If the initial state of the mixture is 300 K and 100 kPa, determine the makeup of the mixture on a mass basis and the internal energy change per unit mass of mixture.
A sample of coarse aggregate weights 1072 grams when oven-dried, 1091 grams when saturated surface-dried, and 667.6 grams when submerged. Calculate the bulk specific gravity, apparent specific gravity, and percent absorption.
A 2.5 hr long uniform rainfall resulted in runoff hydrograph that has the shape of an equilateral triangle. The base of the triangle is 64 hr; the peak flow is 535 cfs; the drainage area is 5.7 mi^2.
