Under steady-state conditions, air at a temperature of 20.0°C, pressure of 1.00 atm, and a velocity of 18.5 m/sec flows over the top surface of a flat-plate heater that is kept at a temperature of 135.0°C. The heater is a circular disk with a diameter of 0.50 meters. The air flowing over the top surface of the disk creates a drag force of 0.25 Newtons. Using the modified Reynolds analogy, calculate the heat transfer rate from the top surface of the plate heater.

The local atmospheric pressure in Denver, Colorado (elevation 1610 m), is 83.4 kPa. Air at this pressure and at 30°C flows with a velocity of 4.8 m/s over a 2.3-m × 8-m flat plate whose temperature is 120°C.

Consider a refrigeration truck traveling at 55 mph at a location where the air temperature is 80°F. The refrigerated compartment of the truck can be considered to be a 9-ft-wide, 8-ft-high, and 20-ft-long rectangular box. The refrigeration system of the truck can provide 3 tons of refrigeration (i.e., it can remove heat at a rate of 600 Btu/ min). The outer surface of the truck is coated with a lowemissivity material, and thus radiation heat transfer is very small. Determine the average temperature of the outer surface of the refrigeration compartment of the truck if the refrigeration system is observed to be operating at half the capacity. Assume the air flow over the entire outer surface to be turbulent and the heat transfer coefficient at the front and rear surfaces to be equal to that on side surfaces. For air properties evaluations assume a film temperature of 80°F. Is this a good assumption?

An object of irregular shape has a characteristic length of L=1 m and is maintained at a uniform surface temperature of Ts = 400 K. When placed in atmospheric air at a temperature of T∞ = 300 K and moving with a velocity of u∞ = 100 m/s, the average heat flux from the surface to the air is 20,000 W/m2. If a second object of the same shape but with a characteristic length of L=5 m, is maintained at a surface temperature of T₂ = 400 K and is placed in atmospheric air at Too 300 K, what will the value of the average convection coefficient be if the air velocity is U = 20 m/s?
