Answer:
The phase current in each line conductor are;
Explanation:
Given the following data;
Red phase = 24kW,
Yellow phase = 18kW
Blue phase = 12kW
Line voltage = 415V
For a star connected system, we have;
The phase sequence for RYB is given by;
<em>For the Red phase;</em>
<em>For the Yellow phase;</em>
<em>For the Blue phase;</em>
For the line neutral;
Substituting we have,

Explanation:
Cylindrical steel rod : diameter ( D ) , length L, uniform temperature T
Initial temp of water : To, heat transfer coefficient between steel rod surface and water : h1
<u>The energy balance equation can be written as :</u>
Rate of convectional heat loss = Rate of decrease in internal energy with respect to time
cp = heat capacity of body, v = volume , р = density of body
attached below is the heat transfer differential equation and boundary and initial conditions
