Problem

Gasoline (density

720\,\text{kg}\,\text{m}^{-3}

) flows through a completely filled siphon from one storage tank to another situated

0.75\,\text{m}

lower. The crest of the tube is

1.20\,\text{m}

above the gasoline level in the upper tank. Atmospheric pressure is

1.01\times10^{5}\,\text{Pa}

. Neglect friction. (a) Calculate the absolute pressure at the crest of the tube. (b) Given the gasoline vapor pressure of

4.0\times10^{4}\,\text{Pa}

, state whether the gasoline will remain in the liquid phase at the crest.
