Question: step by step answer please The temperature distribution for a long fin with uniform cross section is /b=cosh(mL)cosh[(m(Lx)]where=TT A long copper rod of diameter D=1.5cm,L=20cm,
The temperature distribution for a long fin with uniform cross section is /b=cosh(mL)cosh[(m(Lx)]where=TT A long copper rod of diameter D=1.5cm,L=20cm, and thermal conductivity 380 W/mK is in air at 20C with a convection coefficient of 25W/m2K. The temperature at the base is 150C a) If m=5.0m1, the temperature at 5cm from the base of the rod is b) If m=5.0m1, the heat transfer rate from the rod to the air is
