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
