The reading of a pressure meter attached to a horizontal closed pipe is `3 xx 10^(5) Nm^(-2)`. This reading falls to `1 xx 10^(5) N m^(-2)` when the value is opened. What is the speed of water flowing in the pipe?

The reading of a pressure meter attached to a horizontal closed pipe is 3 xx 10^(5) Nm^(-2) . This reading falls to 1 xx 10^(5) N m^(-2) when the valve is opened. What is the speed of water flowing in the pipe?

The reading of pressure-meter fitted in a closed pipe is 4.5 xx 10^(5) Nm^(-2) . On opening the value of the pipe, the reading the meter reduces to 4 xx 10^(5) Nm^(-2) . Calculate the speed of water flowing in the pipe.
