The flow of oil of density $800\text{ kgm}^{-3}$ through a horizontal pipe is streamlined. If the pressure between two points separated by 1m in the tube falls by $1.6\text{ Nm}^{-2}$, then the change in kinetic energy per kg of the liquid between these points is

An incompressible liquid flows through a horizontal pipe having cross-sectional areas \( A \) at one end and \( 2A \) at the other end. If the pressure and velocity of the liquid at the lower cross-section are \( P \) and \( v \), then these values at the other end are

A vessel containing a liquid of density \( d \) moves down with an acceleration \( a \,(a < g) \). The pressure due to the liquid at a depth \( h \) below the free surface of the liquid is

The speed of water flowing out from the small opening at a depth of \(h\) from the surface of water in a large tank is
