The __________ is measured by a piezometric opening.
A
Dynamic pressure
B
Static pressure
C
Total pressure
D
Point velocity
Correct Answer: Total pressure
The total pressure is measured by a piezometric opening. This pressure is the sum of the dynamic pressure and the static pressure in a fluid flow. The piezometric opening helps measure the total energy of the fluid, which includes both kinetic and potential energy. Therefore, in this context, the correct option is Option C: Total pressure
