Problem

A venturi meter is fitted to a horizontal water pipe of diameter

5.0\,\text{cm}

; the throat diameter is

2.0\,\text{cm}

. A mercury manometer connected between the inlet and the throat shows a difference in mercury levels of

15\,\text{cm}

. Take densities: water

=1000\,\text{kg}\,\text{m}^{-3}

, mercury

=13\,600\,\text{kg}\,\text{m}^{-3}

, and

g=9.8\,\text{m}\,\text{s}^{-2}

. Calculate the volume flow rate of water through the pipe.
