In stagnation pressure state, the velocity of the flowing fluid is zero whereas in the static pressure state, the fluid velocity is not equal to zero. Distinguish between static and stagnation pressures. (e.g.) Fluid in a reservoir (or) in a settling chamber. The state of a fluid attained by isentropically decelerating it to zero velocity at zero elevation is referred as stagnation state. Explain the meaning of stagnation state with example.
