Question: 1. Derive the conservation laws for axisymmetric flow in a pipe using control neglect body force work and the energy source. Also, for the energy equation use the thermal equation of state for-ideal gases or incompressible liquids, and assume the Mach number is small for the case of the ideal gas, but do not neglect viscous dissipation. Assume boundary-layer flow, but do not neglect axial conduction.
2. Derive the constant-property energy equation starting. Be sure to state all assumptions made.
