A solid of arbitrary shape is suspended in atmospheric air having a free stream temperature and velocity of 20°C and 100 m/s, respectively. The solid has a characteristic length of 1 m, and its surface is maintained at 80°C. Under these conditions measurements of the convec- tion heat flux at a particular point (x*) on the surface and of the temperature in the bound- ary layer above this point (x*, y*) reveal values of 104 W/m2 and 60°C, respectively. A mass transfer operation is to be effected for a second solid having the same shape but a characteristic length of 2 m. In particular, a thin film of water on the solid is to be evapo- rated in dry atmospheric air having a free stream velocity of 50 m/s, with the air and the solid both at a temperature of 50°C. What are the molar concentration and the species molar flux of the water vapor at a location (x*, y*) corresponding to the point at which the temperature and heat flux measurements were made in the first case?
A piston-cylinder device contains 12 kg of saturated R-134a vapor at 3.2 bar. An electric source supplies 8 A current to a resistor within the cylinder for 4 minutes and there is heat transfer of 400 kJ to the system. During these energy interactions..
