WebA flow process is a physical process in which a fluid (gas or liquid) can enter and leave through a boundary. The volume in the boundary is known as control volume, and it can exchange mass and energy and be used to produce work. In a non-flow process, the fluids are kept in a semi-rigid or rigid vase. WebThen the momentum equation for laminar boundary layer is = ∂ ∂ + ∂ ∂ y u x u u ( ) ρ ρυ 2 2 y u ∂ ∂ µ x P ∂ ∂ − Energy equation: For the shown element control volume as in Figure 8.3.with neglected heat conduction in x-direction and applying energy balance, the energy equation may be written as follows:
