A pressure meter attached to a closed wa...

A pressure meter attached to a closed water tap reads `1.5 xx 10^(5) Pa`. When the tap is opened, the velocity of flow of water is `10 ms^(-1)` and the reading of the pressure meter is

A

`1.5xx10^(5)Pa`

B

`3xx10^(5)Pa`

C

`0.5xx10^(5)Pa`

D

`10^(5)Pa`

Text Solution

Verified by Experts

The correct Answer is:
B
`1.5xx10^(5)=p+1/2xx10^(3)xx10^(2)`
or `p=(1.5 -0.5)xx10^(5)Pa=10^(5)Pa`
