Spring 2009 540.303 TRANSPORT PHENOMENA I Objectives: EXAM 1 EXAM begins at 8:30 AM and ends at 9:50 AM on March 25, 2009 The exam will take place in Maryland Hall 110 and Shaffer Hall 3. CLOSED BOOKS; CLOSED NOTEBOOKS The Equations of Change will be provided to you. You should be able to: 1. Understand and explain the analogies between heat conduction, diffusion and molecular momentum transfer. 2. Explain the mechanisms for molecular momentum transfer in gases and liquids; The effects of temperature and pressure on the viscosity of liquids and gases. 3. Understand the concept of apparent viscosity (non-Newtonian fluids), and be able to use the empirical models (Power Law) that relate shear stress and rate of deformation. 4. Understand the concept that ij is j-directed shear stress that is exerted on faces of constant i; whereas ij is the molecular momentum flux in the i direction as a result of a j velocity component. They are equal in magnitude but in differing directions.

Unformatted text preview: 5. Solve steady-state fluid flow problems for incompressible, Newtonian fluids using the shell balance approach in cartesian and cylindrical coordinates. 6. Understand the physical significance of the boundary conditions on both velocity and shear stress (molecular momentum flux) commonly used at liquid-solid, liquid-liquid and liquid-gas interfaces. 7. Calculate the Reynolds number for flows through simple geometries. 8. Use indicial notation in simple manipulation of scalars, vectors and tensors. 9. Use the equations of change (i.e. Continuity and Motion) to set-up and solve flow problems for incompressible Newtonian fluids; Identify appropriate boundary conditions. 10. Describe the physical origin of the terms that appear in the Equation of Continuity and Equation of Motion. 11. Evaluate forces exerted by fluids on solid surfaces; Determine the direction of force....
