Which of the following is measured by a stagnation tube? OA. pressure +velocity O B. pressure head + velocity head ° C. pressure-elevation 0 D. pressure head + elevation head Reset Selection

Solution

Option B is correct.

Using stagnation tube, we can find pressure head.

By drilling two holes at cross section changing places, we can find velocity also.

By continuity equation, we can say , cross section area and velocity are inversly proportional.

By bernoulli\'s equation, velocity and pressure are inversly proportional.

Using these equations, we can find velocity head also.
