MHT CET 2026 16th April Morning Shift | Fluid Mechanics Question 28 | Physics

A closed pipe containing liquid showed a pressure $P_1$ by gauge. When the valve was opened, pressure was reduced to $P_2$. The speed of water flowing out of the pipe is ($\varrho$=density of water)

$\left[\dfrac{(P_1 - P_2)}{\varrho}\right]^{\frac{1}{2}}$

$\left[\dfrac{2(P_1 - P_2)}{\varrho}\right]^{\frac{1}{2}}$

$\left[\dfrac{(P_2 - P_1)}{\varrho}\right]^{\frac{1}{2}}$

$\left[\dfrac{2(P_2 - P_1)}{\varrho}\right]^{\frac{1}{2}}$

Water flows through a horizontal pipe at a speed 'V'. Internal diameter of the pipe is 'd'. If the water is emerging at a speed '$V_1$' then the diameter of the nozzle is

$\text{d}\sqrt{\dfrac{\text{V}}{\text{V}_1}}$

$\text{d}\sqrt{\dfrac{\text{V}_1}{\text{V}}}$

$\dfrac{\text{dV}}{\text{V}_1}$

$\dfrac{\text{dV}_1}{\text{V}}$
