Q. No.A tube of length \(L\) is shown in the figure. The radius of cross section at the point \((1)\) is \(2~\text{cm}\) and at the point \((2)\) is \(1~\text{cm},\) respectively. If the velocity of water entering at point \((1)\) is \(2~\text{m/s},\) then velocity of water leaving the point \((2)\) will be:
1. \(4~\text{m/s}\)
2. \(8~\text{m/s}\)
3. \(6~\text{m/s}\)
4. \(2~\text{m/s}\)
1. \(4~\text{m/s}\)
2. \(8~\text{m/s}\)
3. \(6~\text{m/s}\)
4. \(2~\text{m/s}\)

A water spray gun is attached a hose of cross sectional area \(30~\text{cm}^2.\) The gun comprises of \(10\) perforations each of cross sectional area of \(15~\text{mm}^{2}.\) If the water flows in the hose with the speed of \(50~\text{cm/s},\) calculate the speed at which the water flows out from each perforation. (Neglect any edge effects)
1. \(100~\text{m/s}\)
2. \(10~\text{m/s}\)
3. \(1000~\text{m/s}\)
4. \(15\times 10^{2}~\text{m/s}\)
1. \(100~\text{m/s}\)
2. \(10~\text{m/s}\)
3. \(1000~\text{m/s}\)
4. \(15\times 10^{2}~\text{m/s}\)
