A) \[\frac{1}{2}{{v}^{2}}\]and\[\frac{P}{\rho }\]
B) \[\frac{1}{2}\frac{{{v}^{2}}}{g}\]and\[\frac{P}{\rho g}\]
C) \[\frac{1}{2}{{v}^{2}}\]and\[\frac{P}{\rho g}\]
D) \[\frac{1}{2}\frac{{{v}^{2}}}{g}\]and\[\frac{P}{\rho }\]
Correct Answer: B
Solution :
: According to Bernouillis equation, \[P+\rho gh+\rho \frac{{{v}^{2}}}{2}=\]constant or \[\frac{P}{\rho g}+h+\rho \frac{{{v}^{2}}}{2g}=\]constant Pressure head\[+\]gravitational head\[+\]kinetic head = constant \[\therefore \]Kinetic head \[=\frac{1}{2}\frac{{{v}^{2}}}{g}\] Pressure head \[=\frac{P}{\rho g}.\].
