Reconsider the problem described in where water jets from a nozzle that has a diameter of 6 mm and impinges on a disk of 4 cm in diameter that is subjected to a uniform heat flux of 70,000 W/m2. Instead of water, consider using air and ethylene glycol as the cooling fluids with the same flow rate (0.008 kg/s) and temperature (20°C) in each case, and determine the temperature on the surface of the disk at radial distances of 3mm and 12 mm from the axis of the jet. Compare the results with those for water obtained in and comment on them.

A compressible fluid is flowing through a pipe with a constriction. The diameter of the narrow section is 1/2 the diameter of the wide section. The density of the fluid in the narrow section is 3/4 the density of the fluid in the wide section. If the velocity of the compressible fluid is 3.600 m/s in the narrow section, then what is the velocity of the fluid in the wide section?
A. 0.675 m/s B. 0.805 m/s C. 0.250 m/s D. 0.333 m/s E. 0.500 m/s
