Unformatted text preview: the pressure decreases at the constant rate of 30 kPa every meter along the flow direction. The top plate is at a uniform temperature of 25 o C while the bottom plate is maintained at 45 o C. Use the mean temperature to evaluate the fluid properties. a) Calculate the velocity and temperature at the location midway between the two plates. b) Calculate the heat fluxes at the two plates. (35 pts) 3. A 6-m long solar collector is made of twelve 50-cm X 3-m flat panels (i.e. the overall dimensions of the collector are 6-m long and 3-m wide). The surface of the collector is maintained at 30 o C. Ambient air at 10 o C flows along the length of the collector at a speed of 2.5 m/sec. Calculate the convective heat transfer rate from the a) first panel b) fifth panel c) tenth panel (35 pts) Note: Q 5 = Q 1-5 Q 1-4...
