Question 1.
What is a differential manometer used for?
Show hintHide hint
Think about what we need to know about the fluid in the system.
Question 2.
What do you calculate first when measuring pressure with a manometer?
Show hintHide hint
Consider where you need to begin for calculations.
3Question 3.
What does the specific gravity tell you about a fluid?
- Weight of the fluid only
- Density relative to water
- Viscosity of the fluid
Show hintHide hint
Think about how densities compare.
4Question 4.
True or False: The pressure at point N can be greater than at point M if the calculated difference is negative.
- True
- False
Show hintHide hint
Reflect on the calculations.
Question 5.
Two tanks contain the same height of liquid A (specific gravity 0.85) 2 m high in one tank and liquid B (specific gravity 0.92) 3 m in the other. What is the pressure difference at the bottom of both tanks?
Show hintHide hint
Don't forget to compare the results once calculated.
Question 6.
A manometer reads oil (SG=0.82) above water (2 m of oil and 4 m of water). Calculate the pressure difference and classify if it is a positive or negative difference.
Show hintHide hint
Check if the values indicate a higher oil pressure or lower water pressure!
