Circular copper rods of diameter d=1mm and length l=25mm areused to enhance heat transfer from a surface that is maintained atts,1=100 deg. c. one end of the rod is attached tothis surface (at x=o), hile the other end (at x=25mm) is joined toa second surface that is maintained at ts,2=0deg. c. air flowing between the surfaces (and over the rods)is also at a temperature t? = 0 deg. c, and has a convectioncoefficient of h=100 w/m2kelvin. a. what is the rate of heat transfer by convection from a singlecopper rod to air? b. what is the total rate of heat transfer from a 1 m x 1 m section of the surface at 100 deg. c, if a bundle of the rods is installed on 4-mm centers?

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.
