Cd= cc * cv.

And the value of Cc& Cv is always less than unity.
Eg : cc = 0.9 and cv = 0.9
Cd = 0.9 * 0.9
Cd = 0.81

Cc is coefficient of contraction Cc= area of orifice ate vena contracts/ area of orifice meter.

For more information search about orifice meter in Google.

What is Cc? Please explain it.

A is right option.

Because of Cd = Cc * Cv.
Cc is less and Cv is high and ultimately, Cd is less than the Cv.

Cd = Cc * Cv.

Where Cc is always less than unity and Cv.
So Cd will be always less than Cv.

I think it's more than.

Kailash said:   8 years ago
Cd is greater than Cc.

Riyaz said:   8 years ago
I think the answer is C.

CD always greater then cc and CV example for venturimeter CD .97 to .98 & cc .64-.67.
