total pressure , I'm confused !
hello :)
i'm new here ...
i'm confused in poits regards pressure
now please correct me if I'm wrong...
1-static pressure is equal to the total pressure if the gas is static (V=0)
2- total pressure is always equal or bigger than the static pressure
3-as the velocity increases the static pressure decrease
if these statements are correct then
1- is the ambient pressure is equal to total pressure and the total pressure is constant at same altitude for any given moving flow
-ex:at sea level-?
2-if the above statement is correct ,then in case of increasing of fluid velocity will its static pressure will equal zero at certain velocity ?
3-

the underlined lines confused me very much the author say that " the static P and T remain UNCHANGED "??
and the stagnation reference depend on the frame of reference?
i can't understand the underline lines...
