A crude oil of specific gravity0.85 flows upward at a volumetric rate of flow of 70litres per second through a vertical venturimeter,with an inlet diameter of 250 mm and a throat diameter of 150mm. The coefficient of discharge of venturimeter is 0.96. The vertical differences betwecen the pressure toppings is 350mm. i) Draw a well labeled diagram to represent the above in formation i) If the two pressure gauges are connected at the tapings such that they are positioned at the levels of their corresponding tapping points, determine the difference of readings in N/CM² of the two pressure gauges ii) If a mercury differential manometer is connected in place of pressure gauges, to the tappings such that the connecting tube up to mercury are filled with oil determine the difference in the level of mercury column.

i)
Draw a well labeled diagram to represent the above in formation
i)
If the two pressure gauges are connected at the tapings such that they are
positioned at the levels of their corresponding tapping points,
determine the
difference of readings in N/CM² of the two pressure gauges
ii)
If a mercury differential
manometer
is connected in place of pressure gauges,
to the tappings such that the connecting tube up to mercury are filled with oil
determine the difference in the level of mercury column.
