A) \[2\sqrt{h\left( H-h \right)}\]
B) \[4\sqrt{h\left( H+h \right)}\]
C) \[4\sqrt{h\left( H-h \right)}\]
D) \[2\sqrt{h\left( H+h \right)}\]
Correct Answer: A
Solution :
Key Idea: The sum of the pressure and the total energy per unit volume of the liquid must be the same at the surface of liquid and at every point of orifice. Form Bernoulli?s theorem, \[P+0+\rho gH=P+\frac{1}{2}\rho {{v}^{2}}+\rho g\left( H-h \right)\]You need to login to perform this action.
