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

1.	The reading of pressure meter attached with a closed water pipe is 3.5 xx 10^(5) Nm^(-2) . On opening the valve of the pipe, the reading of pressure meter is reduced to 3 xx 10^(5) Nm^(-2). Calculate the speed of water flowing out of the pipe.
Answer» SOLUTION :` (P_1 - P_2) = RHO (v_2^(2)- v_1^(2))//22= 0. 5 xx 10 ^(5)= 10 ^(3)v_2^(2) // 2, v_2= 10 MS ^(-1)`
