The reading of a pressure meter attached with a closed water pipe is 3.5 xx 10^(5) N//m^(2). On opening the valve, the reading of the pressure meter is reduced to 3 xx 10^(5) N//m^(2). Calculate the speed of water flowing in the pipe. |

Answer» 10 m/s `(P_(1))/p+1/2v_(1)^(2)=(P_(2))/p+1/2v_(2)^(2)` `(3.5xx10^(5))/(10^(3))+0=(3xx10^(5))/(10^(3))+1/2v_(2)^(2)` `350-300=1/2v_(2)^(2)` `v_(2)^(2)=50xx2=100` `v_(2)=10m//s` So the correct choice is (a). |
