# Heat Transfer - Fluids/ Thermo Equation

I have an equation derived for a simple crossflow heat exchanger

the final equation is listed on the attachment its very simple

there are 2 variables in the equation that I do not know what they are

a C and a roe??

Simply tell me what c and roe are its a specific heat and a density I belive ???

#### Solution Preview

Yes. C = Specific heat of the material (Here, copper) at constant volume and

Rho = Mass density of the material (Here, copper)

Here is how the derivation goes, starting from equation (4.4):

m C (dT/dt) + h A t = h A ...
