Steam in a piston-cylinder assembly undergoes a polytropic process, with $n = 2$, from an initial state where $V_1 = 2.63160 \text{ ft}^3$, $p_1 = 500 \text{ lbf/in}^2$, and $u_1 = 1322.4 \text{ Btu/lb}$ to a final state where $u_2 = 1036.0 \text{ Btu/lb}$ and $v_2 = 3.393 \text{ ft}^3/\text{lb}$. The mass of the steam is $1.5 \text{ lb}$. Changes in kinetic and potential energy can be neglected. Determine the change in volume, in $\text{ft}^3$, the energy transfer by work, in Btu, and the energy transfer by heat, in Btu.

Air flows isentropically through a converging-diverging nozzle. At a section in the diverging portion of the nozzle, $A_2 = 0.450 ft^2$, $p_2 = 4.60 psia$, $T_2 = 310 ^\circ R$, and $Ma_2 = 2.2$. At section (1), in the converging part of the nozzle, determine $A_1$, $p_1$, and $T_1$ if $Ma_1 = 0.66$. Assume ideal behavior. $A_1 = 0.2485 ft^2$ $p_1 = 0.431086 psia$ $T_1 = 609.97 ^\circ R$
