Water flows through a horizontal pipe. At one point, the velocity is 2 m/s and the pressure is 2 m of water column. What is the press another point where the velocity is 3 m/s? (Density of water = 10³ kg/m³)
Water flows through a horizontal pipe. At one point, the velocity is \(2\ \text{m/s}\) and the pressure is \(2\ \text{m}\) of water column. What is the pressure at another point where the velocity is \(3\ \text{m/s}\)?
(Density of water \(=10^3\ \text{kg/m}^3\))
Water flows through a horizontal pipe. At one point, the velocity is $2~m/s$ and the pressure is $2~m$ of water column. What is the pressure at another point where the velocity is $3~m/s$?

Same current is flowing in two different a.c. circuits. First circuit contains only inductance and second contains only capacitance. If the frequency of a.c. is increased in both circuits, the current will
Water is flowing steadily in a river. A and B are the two layers of water at heights $40 \text{ cm}$ and $90 \text{ cm}$ from the bottom. The velocity of the layer A is $12 \text{ cm/s}$. The velocity of the layer B is
A liquid drop splits into \(729\) identical spherical drops. If \(E\) is the original energy and \(U\) is the total resulting energy , then \(E/U = 1/x\). The value of \(x\) is.
A vessel completely filled with water has two holes 'P' and 'Q' at depths '(2h)' and '(8h)' from the top respectively. Hole 'P' is square of side '(a)' and hole 'Q' is a circle of radius '(r)'. If the water flowing out per second from both is same, then side '(a)' is
An electric dipole of dipole moment ' \(p\) ' is aligned parallel to a uniform electric field ' E '. The energy required to rotate the dipole by \(90^\circ\) is \( \begin{bmatrix} \sin 0^\circ = 0, & \sin 90^\circ = 1 \\ \cos 0^\circ = 1, & \cos 90^\circ = 0 \end{bmatrix} \)

A monoatomic ideal gas, initially at temperature $\text{T}_1$ is enclosed in a cylinder fitted with massless, frictionless piston. By releasing the piston suddenly, the gas is allowed to expand adiabatically to a temperature $\text{T}_2$. If $\text{L}_1$ and $\text{L}_2$ are the lengths of the gas columns before and after expansion respectively, then $(\text{T}_2/\text{T}_1)$ is given by}

Water rises up to height ' x ' in a capillary tube immersed vertically in water. When the whole arrangement is taken to a depth 'd' in a mine, the water level rises height ' Y '. If ' R ' is the radius of earth then the ratio (Y x) is
At two points on a horizontal tube of varying cross-section the radii are \(1 \text{ cm}\) and \(0.4 \text{ cm}\), velocities of fluid are \(V_1, V_2\) and pressure difference \((P_1 - P_2)\) between these points is \(4.9 \text{ cm of water}\).
