Answer:
Heat capacity:
The product of specific heat and mass flow rate is known as heat capacity.
[tex]Mass\ flow\ rate =\dot{m}[/tex]
Specific heat = Cp
So Heat capacity C
[tex]C=\dot{m}C_p[/tex]
Heat transfer Q
Q= C ΔT
C is the heat capacity
ΔT is the temperature difference.
When fluid changes phase in heat exchanger then heat capacity of fluid become infinity .It means that temperature difference tends to zero.
[tex]C\rightarrow \infty\ then\ \Delta\ T\rightarrow 0[/tex]
