Oh my god I lost more than an hour over this. Thank you!

Ok here is what I did after your equation: - delete ro*g*hb on the right side since Hb = 0 - remove all the ro (density) I'm left with Vb^2 - Vt^2 = 2 g h Using Eq. of continuity: AtVt = AbVb -> Vb = At/Ab * Vt Then substitute inside Bernoulli and solve for Vt. (At/Ab)^2 * Vt^2 - Vt^2 = 2 g...

Solving with Torricelli I get Vt = 6x10^-3 m/s Solving with Bernoulli I get Vt = 6x10^-4 m/s, a whole order of magnitude smaller. How can it be correct? I know that Torricelli is an approximation, but the solution given by the book uses Torricelli which doesn't seem right to me.

Suppose there is a pressurized gas canister in space, at rest. With a mass "m" of gas inside of it at a pressure "P". Next the valve of the canister is opened. The canister will accelerate in the opposite direction to the valve opening. When all the gas has left the canister, it will be moving...
