An inverted U-tube manometer is used to measure the pressure difference between two pipes $$A$$ and $$B,$$ as shown in the figure. Pipe $$A$$ is carrying oil (specific gravity $$= 0.8$$) and pipe $$B$$ is carrying water. The densities of air and water are $$1.16\,\,kg/{m^3}$$ and $$1000\,\,kg/{m^3},$$, respectively. The pressure difference between pipes $$A$$ and $$B$$ is _______________$$kPa.$$

$$Acceleration$$ $$due$$ $$to$$ $$gravity$$ $$g = 10\,m/{s^2}$$

Consider a frictionless, massless and leak-proof plug blocking a rectangular hole of dimensions $$2R \times L$$ at the bottom of an open tank as shown in the figure. The head of the plug has the shape of a semi-cylinder of radius $$R.$$ The tank is filled with a liquid of density $$\rho $$ up to the tip of the plug. The gravitational acceleration is $$g.$$ Neglect the effect of the atmospheric pressure. GATE ME 2016 Set 2 Fluid Mechanics - Fluid Statics Question 7 English

The force $$F$$ required to hold the plug in its position is

A
$$2\rho {R^2}gL\left( {1 - {\pi \over 4}} \right)$$
B
$$2\rho {R^2}gL\left( {1 + {\pi \over 4}} \right)$$
C
$$\pi {R^2}\rho gL$$
D
$${\pi \over 2}\rho {R^2}gL$$
