Apr 8, 2016 at 16:03 | comment | added | Peter R | I would get a refund on that book | |

Apr 8, 2016 at 15:50 | comment | added | Courage | @Javier yes, but the OP is confused btw the factors $2$ and $\sqrt 2$, how would these factors change the dimension? | |
Apr 8, 2016 at 15:48 | comment | added | Javier | @TheGhostOfPerdition: The only possible relation between $v$, $g$ and $h$ is $v \propto \sqrt{gh}$. | |
Apr 8, 2016 at 15:44 | comment | added | Courage | @Javier I agree that OP is right, but how can one tell it by using just dimensional analysis? | |

Apr 8, 2016 at 15:38 | comment | added | Javier | As far as I can see your analysis is correct. It even follows by dimensional analysis, without doing any math. | |
