A leakage begins in water tank at position P as shown in the figure. The gauge pressure (pressure above that of the atmosphere) at P was `5xx10^(5) N//m^(2)`. If the density of water is `1000kg//m^(3)` the initial velocity with which water gushes out is approximately

A

`3.2ms^(-1)`

B

`32ms^(-1)`

C

`28ms^(-1)`

D

`2.8ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
`Delta p=1/2 rhov^(2)`
`:. v=sqrt((2Delta p)/(rho))=sqrt((2xx5xx10^(5))/(1000))`
`=31.5 m//s`.
