Ratio of cp and cv is greater then one because value of cp is greater then cv.

Since cp > cv & R = cp/cv.
So R(cp/cv) is always greater than 1.
So R(cp/cv) is always greater than 1.

cp/cv = 1.14.
This value is constant.
We denoted it by gama.
This value is constant.
We denoted it by gama.

And r = 1.14 is for air not for all gases. But r>1.

@Prasanth.
Why so? Why Cp is always greater than Cv?

Cp is always greater than Cv, R = Cp>Cv

Justify the equation :
y = cp/cv = 1.14.
y = cp/cv = 1.14.

Cp/Cv = gama.
Which is greater than 1.
Which is greater than 1.

Because Cp is always greater than Cv.
