Properties Of Matter

A liquid of density 750 kgm^\(-\)3 flows smoothly through a horizontal pipe that tapers in cross-sectional area from A₁ = 1.2 \(\times\) 10^\(-\)2 m² to A₂ = \({{{A_1}} \over 2}\). The pressure difference between the wide and narrow sections of the pipe is 4500 Pa. The rate of flow of liquid is ___________ \(\times\) 10^\(-\)3 m³s^\(-\)1.
