3 cards from this section. Quick, good the night before a test.
What is the main function of a manometer?
Think about what devices measure liquid levels or pressures.
Define hydrostatic pressure.
Consider how pressure builds in a pool of water.
What does a manometer measure?
Think about what scientists use to measure fluid levels.
True or False: An inclined manometer is less effective than a vertical manometer for measuring low pressures.
Consider how angles can change measurements.
Calculate the pressure difference between two points in a pipe using a U-tube manometer filled with mercury. If the left arm height is 20 cm and the right arm is 15 cm, what's the pressure in Pa?
Ensure you convert heights to meters and use the density of the specific fluid!
If an inclined manometer reads a height of 25 cm at an angle of 30 degrees, what is the pressure differential?
Remember to break down the inclination into its vertical component before calculating.
