The specifications for an automobile fuel pump state that it should pump \( 1.0 \mathrm{~L} \) of gasoline in \( 40 \mathrm{~s} \) with a suction pressure of \( 150 \mathrm{~mm} \) of mercury vacuum and a discharge pressure of \( 30 \mathrm{kPa} \). Assuming that the pump efficiency is \( 60 \% \), calculate the power drawn from the engine. Note the suction and discharge lines are the same size. Elevation changes can be neglected. The specific gravity (sg) of the gasoline is \( 0.68 \).
