A leakage begins in water tank at position $$P$$ as shown in the figure. The initial gauge  pressure pressure above that of the atmosphere) at $$P$$ was $$ 5 \times 10^{5} N/m^{2}$$ .If the density of water is $$ 1000 kg/m^{3}$$ the initial velocity with which water gushes out is:

Distance $$x_{3}$$ is given by

The correct sketch is

Two holes $$1$$ and $$2$$ are made at depths $$h$$ and $$16 h$$ respectively. Both the holes are circular but radius of hole-$$1 $$ is two times

A viscous liquid flows through a horizontal pipe of varying cross-sectional area, Identify the option which correctly represent,, the variation of heighl of rise of liquid in each vertical tube:

A steel ball of mass $$m$$ falls in a viscous liquid with terminal velocity $$v$$, then the steel ball of mass $$8\ m$$ will fall in the same liquid with terminal velocity:

Uniform speed of $$2 cm$$ diameter ball is $$20 cm/s$$ in a viscous liquid. Then, the speed of $$1 cm$$ diameter ball in the same liquid is:

There is a small hole at the bottom of tank filled with water. If total pressure at the bottom is 3 atm  (1 atm $$= 10^{5} Nm^{-2})$$, then velocity of water flowing from hole is

A box exerts a force of $$420N$$ on a floor. The bottom of the box has an area of $$0.7m^2$$. What is the pressure exerted by the box on the floor?

For the determination of the coefficient of viscosity of a given liquid, a graph between square of the radius of the spherical steel balls and their terminal velocity is plotted. The slope of the graph is given by
