Underground Water Tank – Pressure Variation with Depth
(Municipal engineering + TNPSC / UPSC level)
An underground RCC water tank has a water depth of 6 m.
Questions:
Calculate the pressure at the bottom of the tank in kPa.
Determine the pressure difference between the bottom and a point 2 m below the free surface.
If the tank is filled with oil of specific gravity 0.85, calculate the bottom pressure.
Comment on how fluid density affects pressure variation. Oil Refinery – Simple Manometer Application
(Industry instrumentation + GATE level)
A pipeline carrying oil (specific gravity = 0.9) is connected to a simple U-tube manometer containing mercury. The mercury level difference is 25 cm.
Questions:
Determine the gauge pressure in the pipeline.
Express the pressure in kPa.
If water were used instead of mercury, calculate the new height difference.
Explain why mercury is preferred in manometers.

FLUID KINEMATICS & DYNAMICS
1.Industrial Pipeline – One-Dimensional Flow
(Process industry + TNPSC / GATE level)
Water flows through a pipe whose diameter reduces from 0.4 m to 0.2 m. The velocity at the larger section is 2 m/s.
Questions:
Calculate the velocity at the smaller section using continuity equation.
Determine the discharge through the pipe.
State assumptions made in one-dimensional flow analysis.
Explain whether the flow is compressible or incompressible. 2.Water Supply Main Pipeline
(Municipal engineering + TNPSC level)
A water supply pipeline carries water with a diameter of 0.5 m and velocity 1.8 m/s. The pipe reduces to 0.3 m diameter.
Questions:
Calculate the discharge in the pipeline.
Determine the velocity in the smaller pipe using the continuity equation.
State assumptions made in one-dimensional flow analysis.
Explain why density variation is neglected.
