Water flows in a horizontal pipe. At a point where speed is \(2\,\text{m/s}\), pressure is \(2000\,\text{Pa}\). At another point, speed becomes \(4\,\text{m/s}\). Find pressure at second point. (Density \(= 1000\,\text{kg/m}^3\))

A pipe has cross-sectional areas $4$ cm$^2$ and $1$ cm$^2$. If velocity in the wider section is $2$ m/s, velocity in the narrower section is:

Water flows in a horizontal pipe. At a point where speed is $2$ m/s, pressure is $2000$ Pa. At another point, speed becomes $4$ m/s. Find pressure at second point. (Density $= 1000$ kg/m$^3$)

A steady flow of a liquid of density \(\rho\) is shown in figure. At point \(1\), the area of cross-section is \(2A\) and the speed of flow of liquid is \(\sqrt{2}\;m s^{-1}\). At point \(2\), the area of cross-section is \(A\). Between the points \(1\) and \(2\), the pressure difference is \(100\;N m^{-2}\) and the height difference is \(10\;cm\). The value of \(\rho\) is
Take \(g=10\;m s^{-2}\).
