Question
Five pounds mass of air are heated in a closed, rigid container from $80^{\circ} \mathrm{F}, 15$ psia to $500^{\circ} \mathrm{F}$. Estimate the final pressure of the air and the entropy rise involved.
Step 1
First, we need to find the initial specific volume and specific entropy of the air at the given initial conditions (80°F, 15 psia). We can use the ideal gas law and assume constant specific heats for this purpose. Show more…

Air is expanded from 200 psia and $500^{\circ} \mathrm{F}$ to 100 psia and $50^{\circ} \mathrm{F}$. Assuming constant specific heats, determine the change in the specific entropy of air.
Air initially at 50 psia and $660^{\circ} \mathrm{R}$ expands to atmospheric pressure. The process by which this expansion occurs is defined by the expression $p \Psi^{1.3}=$ constant. Calculate the final temperature and the change in entropy through this process.
Five kilograms of air is cooled in a closed tank from 250 to $50^{\circ} \mathrm{C}$. The initial pressure is 3 MPa. Compute the changes in entropy, internal energy, and enthalpy. Show the process state points on a $T s$ diagram.
