Density
Density
These are the three common phases of matter.
What are solids, liquids, gasses?
This is defined as force per unit area.
What is pressure?
This principle states that pressure applied to a confined fluid is transmitted throughout the fluid.
What is Pascal's Principal?
This type of fluid flow is smooth and orderly.
What is laminar flow?
This property describes the internal friction of a fluid.
What is viscosity?
Liquids of gases belong to this category of matter because they can flow.
What are fluids?
This SI unit of pressure equals one newton per square meter.
What is the pascal?
This upward force is exerted on an object submerged in a fluid.
What is buoyant force?
This type of fluid flow contains irregular motion and eddies.
What is turbulent flow?
This theorem describes the speed of fluid exiting an opening in an open tank.
What is Toricelli's theorem?
This property is defined as mass per unit volume.
What is density?
The pressure exerted by a liquid increases as this increases.
What is depth?
According to Archimedes' principle, the buoyant force equals the weight of this.
What is the displaced fluid?
This equation states that the product of cross-sectional area and fluid speed remains constant for an incompressible fluid.
What is the equation of continuity?
This principle helps explain airplane lift through differences in air speed and pressure.
What is Bernoulli's principle?
This is the SI unit for density.
What is kg/m3 ?
This type of pressure measures pressure above atmospheric pressure.
What is gauge pressure?
An object with a density lower than that of the surrounding fluid tends to do this.
What is rise and float?
When an incompressible fluid enters a narrower section of pipe, its speed does this.
What is increase?
According to Poiseuille's equation, flow rate is proportional to the tube's radius raised to this power.
What is the fourth power?
Water has a density of 1 g/cm³, equivalent to this value in kg/m³.
What is 1,000 kg/m³?
If atmospheric pressure is 100 kPa and gauge pressure is 30 kPa, this is the absolute pressure.
What is 130 kPa?
For a floating object, the fraction of its volume submerged equals this density ratio.
What is the object's density divided by the fluids density?
According to Bernoulli's principle, this happens to pressure when fluid speed increases under the relevant conditions.
What is decrease?
If an artery's radius is halved, this factor increase in pressure difference is needed to maintain the same flow rate.
What is 16?
