    Find center temperature and maximum temperature in the wall.

    Given that in problem
    Radius of wire r = 0.001268m
    Length of wire L= 0.9m
    Average conductivity k = 22.5 W/m.K
    Resistance R = 0.126 ohms
    Current = 200A
    Wall temperature Twall = 422.1K

    Assignment no.5
    Problem5.1

    1. Basic concept of this assignment is related to
    (a) current
    (b) Resistance
    (c) Volumetric heat generation
    In this type of problem we use simple Ohms law

    Q = I2*R
    Where R = resistance

    Solution:
    Given that in problem
    Radius of wire r = 0.001268m
    Length of wire L= 0.9m
    Average conductivity k = 22.5 W/m.K
    Resistance R = 0.126 ohms
    Current = 200A
    Wall temperature Twall = 422.1K
    So total energy generation rate qg = I2*R
    = (200)2*0.126
    ...

    Solution Summary

    Center temperature and maximum temperature of a Wall are calculated from given data is analyzed. The solution is detailed and well presented.
