1. Write the energy equation for a fluid element. What is dissipation function? When is its effect significant? When can it be neglected?

2. Express the similarity of momentum and energy equations for flow over a flat plate. How are their solutions identical for fluids having n =
.

3. Explain the principle of similarity applied to heat trans fer. How are the relevant dimensionless parameters derived from the appropriate differential equations?
