Interpretation: The amount of heat added to a fluid is to be calculated when there is a change in internal energy of the system followed by other energy changes.
Concept introduction: The Energy flow in the fluid across a control surface is given by the following equation,
The total heat is thus given as the sum of internal energy, kinetic energy, potential energy and pressure energy of the system.
The equation (1) can be written after simplifying as,
Here,
P2- P1 is change in Pressure of the fluid
u2- u1is change in Internal energy of the fluid
v22 − v12 is change in velocity of the fluid
Z2 − Z1 is change in position of the fluid
m is the mass flow rate of the fluid
