Correct Answer - Option 2 : Dynamic Head: Sum of datum head and velocity head
Concept-
We have the energy equation,
\(\frac{P}{{\rho g}} + \;\frac{{{v^2}}}{{2g}} + Z = Constant\)
Where
\(\frac{P}{{\rho g}} =\) Pressure head or Static head
V2 / 2g → Velocity head / Dynamic head / Kinetic head
Z = datum head
\(\frac{P}{{\rho g}} + \;\frac{{{v^2}}}{{2g}}\rightarrow\) Stagnation Head
\(\frac{P}{{\rho g}} + Z \to \) Peizo metric Head
Dynamic Head is the only velocity head so option b is incorrectly matched.
