 Title: Water eject from a hole in a water tank Post by: Fu-Kwun Hwang on June 25, 2005, 10:22:52 am If there is a hole in a water tank, water will shot out due to water pressure.You can drag the hole up and down to change its position.Click show baseline checkbox, drag the hole up and down , and find out when the horizontal displacement is maximum?Relation between horizontal velocity vx and height h(height between water level and the hole).$\rho g h =\frac{1}{2} \rho v_x^2$ , so $vx=\sqrt{2\,g\, h}$
