A) \[60N{{m}^{-2}}\]
B) \[180\,N{{m}^{-2}}\]
C) \[7500N{{m}^{-2}}\]
D) \[12500N{{m}^{-2}}\]
Correct Answer: C
Solution :
[c] Pressure difference \[{{P}_{2}}-{{P}_{1}}=\frac{1}{2}\rho (v_{2}^{2}-v_{1}^{2})\] \[=\frac{1}{2}\times 1.2\left( {{(150)}^{2}}-{{(100)}^{2}} \right)=7500N{{m}^{-2}}\]You need to login to perform this action.
