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.

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.

When a tap is closed, the manometer attached to the pipe reads 3.5xx10^(5)Nm^(-2) . When the tap is opened, the reading of manometer falls to 3.0xx10^(5)Nm^(-2) . The velocity of water in the pipe is

A manometer connected to a closed tap reads 4.2 xx 10^(6) N/m^(2) and when tap is opened the readin of manometer falls to 4.0 xx 10^(6) N/m^(2) . Find the speed of flow of water.

One end of a horizontal pipe is closed with the help of a velve and the reading of a barometer attached in the pipe is 3xx10^(5) pascal When the value in the pipe is opened then the reading of barometer falls to 10^(5) pascal the velocity of water flowing through the pipe will be in m/s-

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 manometer connected to a closed tap reads 3.5xx10^(5)N//m^(2) .When the value is opened, the reading of manometer fall is 3.0xx10^(5)N//m^(2) , then velocity of flow of water is

The pressure of water in a water pipe when tap is opened and closed is respectively 3xx10^(5)Nm^(-2) and 3.5xx10^(5)Nm^(-2) with open tap the velocity of water flowing is (a). 10m//s (b). 5m//s (c). 20m//s (d). 15m//s

A manometer connected to a closed tap reads 4.5 xx 10^(5) pascal. When the tap is opened the reading of the manometer falls is 4 xx 10^(5) pascal. Then the velocity of flow of water is

A hose-pipe of cross-section area 2cm^(2) delivers 1500 litres of water in 5 minutes. What is the speed of water in m/s through the pipe?
