Specific Heats for Incompressible Fluids

[Spectre5]

Given the following equation:

Cp = Cv + R

Where Cp is specific heat (constant pressure), Cv is specific heat (constant volume), and R is the universal gas constant.

However, my book states that for an incompressible fluid, Cp = Cv.

How can this be the case given the above equation? R is a constant for any given fluid, so why is is zero for an incompressible fluid?

Nevermind, I think I figured it out

Can you explain to me what you figured out then (or someone)?
I don't understand how the specific heat for an ICL is supposed to be determined.

The specific heat is usually provided for you in the problem statement, or in a table somewhere in the textbook.
