A thin V-shaped glass tube is fixed in the vertical plane as shown. Innitially the left part of the tube contains a column of water of length `d=sqrt(2)`m. A valve at the bottom of the tube prevents the water from moving to right part. At some time, the valve is quickly opened neglecting friction find the time (in seconds) it takes for the water to move completely into the right part of the tube. (Take `g=pi^(2)m//s^(2))`

A U-tube of small and uniform cross section contains water of total length 4H the height difference between the water columns on the left and on the right is H when the valve K is closed, the valve is suddenly open, and water is flowing from left to right. ignore friction find the speed of water when the heights of the left and the right water columns are the same.
