The pressure of water in a pipe when tap is closed are 5.5 x 10^5N/m^2. When tap gets open, pressure reduces to 5×10^5N/m^2. The velocity with which water comes out on opening the tap is pressure reduces to 5x10^5N/m^2. The velocity with which water comes out on opening the tap is The pressure of water in a pipe when tap is closed are 5.5 x 10^5N/m^2.
