Air within a piston–cylinder assembly, initially at 30 lbf/in.2, 510°R, and a volume of 6 ft3, is compressed isentropically to a final volume of 1.2 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, and (d) work, in Btu.
