C_v

C_v= du/dT
C_p

C_p = dh/dT
When can ideal gas law of state be used for non ideal gas?
- High temps
- Low pressures
R

R = ^-R^- / m
ideal gas law of state

Pv = RT
isobaric

n = 0
isometric

n = +- inf
isothermal/ideal gas

n = 1
conservation of energy control volume

ΔE = Q_cv - W_cv + m_i(h_i + V_i²/2 + gz_i) - m_e(h_e + V_e²/2 + gz_e)
nozzle
- Pressure down
- Volume up
- Change in h and V
Diffuser
- Pressure up
- Volume down
- Change in h and V
Turbine
- change in Pv so
- change in h
heat exchanger
- change in u so
- change in h
throttling device

h2 = h1
