Consider a mixture of neon (Ne, MW = 20.18 g/mol) and krypton (Kr, MW = 83.80 g/mol) at a temperature T = 309.15 Kelvin. The total pressure of the gas mixture is p = 811.4 torr, and the density of the gas mixture is 2.556 g/L. Find the following. a) The volume occupied by 1.000 moles of the gas mixture. b) p(Ne), the partial pressure of neon gas in the gas mixture. For the conditions in the problem you may...

Air within a piston–cylinder assembly, initially at 15 lbf/ in.2, 510°R, and a volume of 6 ft3, is compressed isentropically to a final volume of 3 ft3. Assuming the ideal gas model with k = 1.4 for the air, determine the: (a) mass, in lb. (b) final pressure, in lbf/in.2 (c) final temperature, in °R. (d) work, in Btu.

Problem 2.3. An ideal ramjet is to fly at 20,000 ft with a Mach number of 3.5. The burner exit total temperature is to be 3200 °?? and the engine will use 145 lbm/s of air. The heating value of the fuel is 18,500 Btu/lbm. What is the diameter of the rounded exit, thrust, dimensionless thrust, and TSFC at this condition?

During a constant pressure, nonflow (closed system) process, a gas loses 103 BTUs of heat to the surroundings while it's volume changes from 2.2 ft3 to 0.7 ft3. If the temperature of the gas decreases by 7 oF and the system contains 3.3 lbm of gas, find the absolute pressure of the system in lbf/in2. cV for this gas is 0.229 BTU/lbm-oF. (Hint: For this process, ∆U = mcV∆T even though the process is not carried out at constant volume). State...

Combined Gas Relationship Since the Ideal Gas Law produces a constant (R), it can be used to look at a gas sample in which initial and final conditions have changed. The combined gas relationship is as follows P.V R=P.V2 n, T n2 T2 where P, Vi,and T, and n, are the initial pressure, volume, temperature, and number of moles of gas. The final conditions are represented by P, V2, T2 and n2. If any of the conditions in the initial...
