Problem la - by hand 0.1 lbm of air (ideal gas) initially at 50 psia and 100 F in a cylinder with a movable piston undergoes the following two-part process.

First the air is expanded adiabatically to30 psia and 24 F, then it is compressed isobarically to half of its initial volume. Calculate the temperature at State 3(after the isobaric compression). Then, use the air tables in your supplement to calculate the work and heat from: a. State 1 to State 2 b. State 2 to State 3 c. Total for whole process
