5.3.1: Non Deformable Control Volume

  • Page ID
  • When the control volume is fixed with time, the derivative in equation (??) can enter the integral since the boundaries are fixed in time and hence,

    Continuity with Fixed b.c.

    \[ \label{mass:eq:intSrho}
    \int_{V_{c.v.}} \dfrac{d\,\rho}{dt} dV = -\int_{S_{c.v.}} \rho\,U_{rn} \, dA

    Equation (??) is simpler than equation (??).
