In a vertical pipe conveying oil of specific gravity 0.8, two pressure gauges have been installed at A and B where the diameters are 16cm and 8cm respectively. A is 2 meters above B. The pressure gauge readings have shown that the pressure at B is greater than at A by 0.981N/cm². Neglecting all losses, calculate the flow rate. If the gauges at A and B are replaced by tubes filled with the same liquid and connected to a U-tube containing mercury, calculate the difference of level of mercury in the two limbs of the U-tube.

civil engineering.

In a vertical pipe conveying oil of specific
gravity 0.8, two pressure gauges have been
installed at A and B where the diameters
are 16cm and 8cm respectively. A is 2
meters above B. The pressure gauge
readings have shown that the pressure at B
is greater than at A by 0.981N/cm².
Neglecting all losses, calculate the flow rate.
If the gauges at A and B are replaced by
tubes filled with the same liquid and
connected to a U-tube containing mercury,
calculate the difference of level of mercury
in the two limbs of the U-tube.
