#### Solution Preview

Please see the attached file

(a) H = Pressure/ density (m2/s2)

V = speed of flow (m/s)

z = height from the datum (m)

Q = the heat added per unit time to the stream tube by conduction divided by the mass flow rate through the tube, (m2/s2)

W = the viscous working rate on the environment of the tube divided by the ...

#### Solution Summary

The energy equations for compressible gas are examined for fluid mechanics.
