Air at 30℃ is being heated by both the top and bottom surfaces of a flat plate. The plate has a length of 0.8 meters along the flow direction and a width of 0.4 meters. Air flows over the plate at a velocity of 5 m/s. Both surfaces of the plate are maintained at a constant temperature of 100℃. Determine the rate of heat loss from the plate.

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
