4 cards from this section. Quick, good the night before a test.
What is the formula used to calculate pressure in a piezometer?
Think about how the height and density relate to the pressure measurement.
What type of manometer uses a straight tube to measure pressure?
Consider the shape of the tube used in this device.
What is the primary purpose of a piezometer?
Focus on what device measures pressure in fluids.
True or False: A differential manometer can measure absolute pressure.
Think about what 'differential' means.
A U-tube manometer contains water on one side and oil on the other. The height of the oil column is 0.2 m, and its density is 850 kg/m³. Determine the water height in the manometer if the atmospheric pressure is 101325 Pa.
Equate the pressure of both sides to find the unknown height.
A differential manometer is used between two tanks with liquid A (density = 950 kg/m³) and liquid B (density = 1200 kg/m³). If the pressure in tank A is 150 kPa and in B is 200 kPa, what is the pressure difference displayed on the manometer?
Use the densities and heights to figure out how pressure impacts fluid columns.
