A liquid of density

600\ \mathrm{kg/m^3}

is flowing steadily in a tube of varying cross-section. The cross-section at a point A is

1.0\ \mathrm{cm^2}

and that at B is

20\ \mathrm{mm^2}

. Both the points A and B are in same horizontal plane, the speed of the liquid at A is 10 cm/s. The difference in pressures at A and B points is Pa.

We corrected a printing error in the original paper

Source printed “A liquid of density 600 kg/m $^3$ flowing steadily” (verb missing); “The difference is pressures”.
