A) \[P-\frac{3\rho {{v}^{2}}}{2}\]
B) \[P-\frac{\rho {{v}^{2}}}{2}\]
C) \[P-\frac{3\rho {{v}^{2}}}{4}\]
D) \[P-\rho {{v}^{2}}\]
Correct Answer: A
Solution :
\[\operatorname{For} velocity\to small v\] \[\operatorname{For} voltage \to capital V\] Apply bernoulli?s theorem \[\operatorname{P}+\frac{1}{2}\rho {{v}^{2}}+z={{P}_{1}}+\frac{1}{2}\rho {{(2v)}^{2}}+z\] \[\operatorname{P}+\frac{1}{2}\rho {{v}^{2}}={{P}_{1}}+2\rho {{\operatorname{v}}^{2}}\] \[{{P}_{1}}=P-\frac{3}{2}\rho {{\operatorname{v}}^{2}}\]You need to login to perform this action.
