A pump and its horizontal intake pipe are located 12 m beneath the surface of a reservoir. The speed of te water in the intake pipe causes the pressure there to decrease, in accord with Bernoulli's principle. Assuming nonviscous flow, what is the maximum speed with which water can flow through the intake pipe?(adsbygoogle = window.adsbygoogle || []).push({});

I tried solving the problem like this:

density*g*12 = (density*v^2)/2

v^2 = 24*9.8

v = 15.336 m/s

It's not the right answer. The answer is 21m/s. Why is this? please help thanks...
