1. Consider laminar fully developed flow in a parallel-plate channel of spacing 26. Find the velocity distribution and the friction factor. W y 2b x 2. Consider laminar fully developed flow in a parallel-plate channel of spacing 2b exposed to constant wall heat flux. Find the fully-developed temperature distribution and the Nusselt number. 3. Consider laminar hydrodynamically fully developed, thermally developing flow in a parallel-plate chan- el of spacing W. Non-dimensionalize the energy equations using $U = \frac{u}{\bar{u}}$, $\theta = \frac{T_w - T}{T_w - T_0}$, $Y = \frac{y}{W}$, and $Z = \frac{z/W}{RePr}$. What are the appropriate boundary conditions if the wall temperature is constant? 4. Consider laminar hydrodynamically fully developed flow. Estimate the thermal entrance length using the supplied MATLAB code tdpipe.m and compare with Eq. (8.23). 5. Consider laminar flow in a parallel-plate channel of spacing W exposed to constant wall temperature. Assume that the velocity distribution is uniform with $u = \bar{U}$, i.e. slug flow. Find the temperature distribution and the Nusselt number.

1. The figure below shows two options for conditioning atmospheric air at steady state. In each case, air enters at 15°C, 1 atm, and 20% relative humidity with a volumetric flow rate of 150 m³/min and exits at 30°C, 1 atm, and 40% relative humidity. One method conditions the air by injecting saturated water vapor at 1 atm. The other method allows the entering air to pass through a soaked pad replenished by liquid water entering at 20°C. The moist air stream is then heated by an electric resistor. If the surrounding temperature is 25°C, which of the two options is preferable? Discuss.
