Q1:A 200 ft'tank contains agas with specific gravity 0.75 at 94 F and 2120 psig the gas contains 12mol% coz what is the density and number of moles of gas in the tank? Q2:A samples of three types of natural gas come frome different reservoirs with volums 10,20,30 ft respectively mixed together at 2200 psia and 150F.the Pseudo-critical temperatures for the samples are 340R. 370R, 385R respectively. R. PORT Calculate: Z 1-the gas mixtur compressibility factor under mixing conditions. 2-the gas mixtur formation volume factor under mixing conditions. PMI Va
