What is the value of kinetic energy thickness?

A. δ** = \(\int_0^∞ \frac {u}{U_e}\big [ \)1 – \(\big ( \frac {u}{U_e}\big )^2 \big ] \)dy
B. δ** = \(\int_0^∞ \frac {u}{U_e} \big [ \)1 – \(\frac {u}{U_e}\big ] \)dy
C. δ** = \(\int_0^∞ \big [ \)1 – \(\frac {u}{U_e} \big ] \)dy
D. δ** = \(\int_0^∞ \frac {u}{U_e} \big [ \)1 + \(\frac {u}{U_e}\big ] \)dy
Answer» B. δ** = \(\int_0^∞ \frac {u}{U_e} \big [ \)1 – \(\frac {u}{U_e}\big ] \)dy
