A pitot static tube is used to measure the velocity of water in a pipe. The stagnation pressure head is 6 m and static pressure head is 5 m. Calculate the velocity of flow assuming the coefficient of velocity of tube equal to 0.98.

While applying the momentum and energy equations in fluid mechanics, a control volume is often referred to the
