A tank with a small hole at the bottom has been filled with water and kerosene (specific gravity 0.8). The height of water is 3 m and that of kerosene 2 m. When the hole is opened the velocity of fluid coming out from it is nearly : (take g=10 ms-2 and density of water =103 kg m-3)
10.7 ms-1
9.6 ms-1
8.5 ms-1
7.6 ms-1
As we have learned
Torricelli's Theorem / Velocity of Efflux -
In fluid dynamics relating the speed of fluid flowing out of an orifice.
- wherein
According to torcellli theorem
velocity of efflux =
Left density of water is
Density of kerosene = 0. 8
