Vedclass · Answer

(C) In fluid mechanics, specifically Bernoulli's equation, the energy per unit weight of a fluid is expressed in terms of 'heads':$1$. Velocity head: This represents the kinetic energy per unit weight of the fluid, given by $\frac{v^2}{2g}$. Thus, $(a-iii)$.$2$. Pressure head: This represents the pressure energy per unit weight of the fluid, given by $\frac{P}{\rho g}$. Thus, $(b-i)$.$3$. Potential head: This represents the potential energy per unit weight of the fluid, given by $h$. Thus, $(c-ii)$.Therefore, the correct matching is $(a-iii), (b-i)$.

Column - $I$	Column - $II$
$(a)$ Velocity head	$(i)$ $\frac{P}{\rho g}$
$(b)$ Pressure head	$(ii)$ $h$
$(c)$ Potential head	$(iii)$ $\frac{v^2}{2g}$

Different heads are in Column - $I$ and their formulas are given in Column - $II$. Match them appropriately.
