A horizontal pipe line carries water in a streamline flow. At a point along the pipe where the crosssectional area is 10 cm, the water velocity is 1 ms and the pressure is 2000 Pa. What is the pressure at another point where the crosssectional area is 5 cm?
Find pressure on swimmer at a depth of 10 m in water.
If there were no gravity, which of the following will not be there for a fluid?
A tank full of water has a small hole at its bottom. If one-fourth of the tank is emptied in $t_1$ seconds and the remaining three fourths of the tank is emptied is $t_2$ seconds, then ratio $(t_1/t_2)$ is
A piece of brass (alloy of copper and zinc) weighs 12.9 g in air. When completely immersed in water it weighs 11.3 g. What is the mass of copper contained in the alloy ? (Specific gravities of copper and zinc are 8.9 and 7.1 respectively)
If the surface tension of water is ${0.06\, N\, m^{-1}}$, then the capillary rise in a tube of a diameter 1 mm is (Take $\theta$ = 0?)
Two capillary tubes of radii 0.2 cm and 0.4 cm are dipped in the same liquid. The ratio of heights through which liquid will rise in the tubes is
A block of wood floats in water with $\left( \frac{4}{5} \right)^{th}$of its volume submerged. If the same block just floats in a liquid, the density of the liquid (in Kg m$^{-3}$) is
A raft of wood of mass $120\, kg$ floats in water. The weight that can be put on the raft to make it just sink, should be $\left(d_{ \text{raft} }=600\, kg / m ^{3}\right)$
The soap bubbles radii in the ratio $2 : 1$ ratio of excess pressure inside there is:
Two vessels A and B of cross-section as shown in figure contain a liquid upto the same height. As the temperature rises, the liquid pressure at the bottom (neglecting expansion of the vessels) will:
According to Newton, the viscous force acting between liquid layers of area A and velocity gradient $ \frac{\Delta \upsilon }{\Delta z} $ is given by $ F=\eta A\frac{\Delta \upsilon }{\Delta z} $ where $ \eta $ is a constant called coefficient of viscosity. The dimension of $ \eta $ are:
A boat with scrap iron in it is floating in a small tank of water. If the iron is thrown into the tank the level of water in the tank:
