The Vestas V$236-15\mathrm{.}0$ Wind Turbine generates a maximum of $15\mathrm{.}0$ MW of power. $($This is called the rated power.$)$

If the V$236-15\mathrm{.}0$ generates $15\mathrm{.}0$ MW of power in $15\frac{m}{s}$ for sea level conditions $($air density: $1\mathrm{.}225k\frac{g}{m^3}),$ what is the power coefficient for the turbine at this condition?

If the V$236-15\mathrm{.}0$ was NOT limited to generating of $15\mathrm{.}0$ MW of power, what is the maximum theoretical power that turbine could generate in $15\frac{m}{s}$ winds for sea level conditions?
