Hello students here we have to discuss a fundamentals of the energy balance analysis.
00:07
So first see about the heat transfer.
00:15
The heat transfer is a within a heat exchange here occurs between the two fluid streams.
00:23
So example we have a hot fluid and cold fluid.
00:35
So the heat is transferred from the hot fluid to the cold fluid.
00:40
So we can write down the rate of heat transfer as rate of heat transfer that can be written as q equal to m c p del t.
01:09
This is our equation number one.
01:11
So here q is the heat transfer rate and m is the mass flow rate of the fluid and c p is the specific heat of the fluid and del t is the temperature difference between them.
01:25
So second we have to discuss about the energy balance equation.
01:33
Energy balance equation that is q1 plus q2 equal to w plus del e.
01:53
This is our equation number two...
