Figure 1 shows cylindrical solid wall, where is the thermal conductivity. Calculate q for a copper tube ( = 400 . ) of length = 300 with an outer radius of 2 = 5 and an inner radius of 1 = 3. The external temperature is 2 = 20 and the internal temperature is 2 = 100 Figure 1. cylindrical solid wall 1.1. Use the equation below to solve for the steady-state heat conduction : (Note: command script must include student name AND student number). = 2 1 2 ( 2 1 ) (6) 1.1.1. Fix to 15 significant figures (3) 1.1.2. Fix to 5 significant figures (3) 1.1.3. Return the nearest integer (3) 1.2. Using the zeros commands create a 6 6 matrix (2) 1.2.1.
