1) Since we knew that the air in the system was an ideal gas we could apply pV=mRT to
figure out our mass. We then could use the first law of thermodynamics to find our work
and internal energy and relate that bac

1) In order to solve this problem I knew we would have to take a mass, entropy, and energy
balance equations to get out variables we wanted to solve for. Then by elimination
variables we knew we could rul

1) In order to solve this problems, I knew we needed to use the first law of
thermodynamics to find the work done by the shaft. We need to draw and label a FBD in
order to find all forces and account for them in our work equ

1) In order to solve the problem for the incompressible part I just used the normal
pressure equation using the specific weight of air. By thinking about it this way, I felt
like it was just a normal pressu

1) To solve this problem we need to be able to recognize what properties are included
when a system is at steady state. Also, we need a good understanding of the ideal gas
law in order to find our unknown q

Thermo Mastery Problem 4.129
1) In order to approach this problem, I used the conservation of mass and conservation of
energy equations along with our specific heat equation in order to solve for the variable
T. Then I used our normal

The current US energy structure requires us to remain dependent on foreign energy
sources in order to sustain our current energy consumption. And for us to remain dependent on
foreign energy, means we are at

1) Since we knew the system was at steady state we could use conservation of mass in
order to find the other two mass flow rates. Treating the gas as ideal we could also use
the ideal gas law in order to find our
