What are the two factors that affect the pressure of the fluid?
For incompressible fluids it is its density and the height of the fluid over the point where the pressure needs to be determined
Describe the reason a fluid exerts pressure on an object immersed in the fluid?
The pressure that a fluid exerts depends on the density and the depth of the fluid.
What causes pressure in fluid's?
All of the forces exerted by the individual molecules in a fluid add together to make up the pressure exerted by the fluid
Discuss the possible variations that would affect pressure if hot fluid is used in a pressure calibrator?
Expansion of the Fluid: When the fluid is heated, it expands, increasing its volume. This expansion can lead to an increase in pressure within the calibrator. Expansion of the Calibrator Components: The heating of the fluid can also cause expansion of the calibrator's components, such as the chamber or seals, leading to changes in internal volume and pressure. Changes in Fluid Properties: Heating the fluid can alter its viscosity and density, affecting its behavior and pressure readings within the calibrator. Thermal Gradients: Variations in temperature within the calibrator can create thermal gradients, causing uneven expansion and pressure distribution. Temperature-Pressure Relationship: The pressure measured by the calibrator can be influenced by the temperature-pressure relationship of the fluid, which may not be linear.
How does increasing attitude affect air pressure and density?
as the altitude increase, the effect of gravity become more insignificant on air and the air become more disperse or thinner hence it does affect the air pressure and density by decreasing both air pressure and density of the air.
What are the two factors that affect the pressure of the fluid?
For incompressible fluids it is its density and the height of the fluid over the point where the pressure needs to be determined
What is the difference between a compressible fluid and an incompressible fluid?
The density of a compressible fluid changes with pressure, while the density of an incompressible fluid is not affected by pressure (assuming isothermal conditions).
What are the factors that affect viscosity?
Temperature, concentration, sometimes also internal fluid velocity. Moreover density, type of liquid, surface where it flows, viscous drag.
Describe the reason a fluid exerts pressure on an object immersed in the fluid?
The pressure that a fluid exerts depends on the density and the depth of the fluid.
How does altitude affect density and air pressure?
Altitude has a large affect on the air pressure and air density. Air density reduces with altitude and air pressure reduces with altitude as well.
How does altitude affect the density and pressure of air?
Altitude affects density and pressure by decreasing when it increases.
How does the density of the air affect pressure?
Pressure affects the density of air by increase of pressure increases the density
Does the pressure vary according to the density of a fluid?
tellme something about pressure of fluids
How does altitude affect density and pressure?
Air pressure decreases as altitude increases. As air pressure decreases, so does density.
How does increasing the density of a gas affect the pressure?
By increasing the density of a gas its air pressure will subsequently increase.
How does increasing the density of gas affect its pressure?
