What does a manometer measure?
Think about how fluid height in a tube relates to pressure.
What is the specific gravity of a fluid?
Consider it a comparative measure of densities.
What is the primary purpose of a manometer?
Think about the relationship between fluid heights and pressure.
True or False: An inclined manometer is less sensitive than a vertical manometer.
Consider how inclination affects measurements.
A gas pipeline is connected to an inclined manometer with a reading of 150 mm of oil (specific gravity 0.80) at an angle of 25 degrees. Calculate the corresponding gauge pressure in Pascals.
Don't forget to convert mm to meters.
You have an inclined manometer showing 120 mm deflection of water and 80 mm of oil (specific gravity 0.85) in different segments. Determine the total pressure difference between the two fluids at the entry point.
Use the relation of specific gravities effectively while converting measurements.
