... In these collisions energy between the particles and the lattice is exchanged. This is modeled by the creation and destruction of pseudo particles (phonons). In crystals this is by far the most important collision mechanism (more frequent than particle - particle collisions). The energy exchange is ...

... Problem 2 Water of constant density =1000kg/m3 flows through a horizontal 2-D channel shown in Fig.2.2. The flow is in steady state. The entrance of the pipe has a height of H1=2m and the outlet has H2=4m. The velocity is uniform (u1 = 1m/s) at inlet. The flow at outlet is laminar and fully develop ...
