10 Questions
Match the following flow types with their descriptions:
Laminar Flow = Paths of individual particles do not cross or intersect Turbulent Flow = Path lines are irregular curves and continuously cross each other Steady Flow = Discharge passing a given cross section is constant with time Uniform Flow = Average velocity at every cross-section is the same for a given length of stream
Match the following terms with their definitions:
Discharge = Amount of fluid passing a section of a stream in unit time Volume Flow Rate = Product of mean velocity and cross-sectional area Reynolds’ number = Defines laminar or turbulent flow based on its value Mass Flow Rate = Expression of discharge in terms of mass passing through a section of a stream
Match the following flow types with the Reynolds’ number ranges defining them:
Laminar Flow = Reynolds’ number less than 2100 Turbulent Flow = Reynolds’ number greater than 2100 Highly Controlled Laminar Flow = Reynolds’ number up to 50,000 in laboratories Unlikely Laminar Flow Condition = Reynolds’ number as high as 50,000 in practice
Match the following flow terms with their alternative expressions:
Discharge = Also expressed as mass flow rate and weight flow rate Steady Flow = Occurs if the discharge passing a given cross section is constant with time Uniform Flow = Said to be uniform if the average velocity at every cross-section is the same Laminar Flow = Also known as flow where paths of individual particles do not cross or intersect
Match the following flow terms with their primary usage in fluid dynamics:
Discharge = Measure of amount of fluid passing a section of a stream in unit time Laminar Flow = Characterized by paths of particles not crossing or intersecting Turbulent Flow = Path lines are irregular and continuously cross each other Reynolds’ number = Defines laminar or turbulent flow based on its value
Discharge is also expressed as ______ flow rate and weight flow rate
mass
The flow is said to be ______ when the paths of the individual particles do not cross or intersect
laminar
The paths of particles of a stream flowing with ______ motion are neither parallel nor fixed but it aggregates to forward motion of the entire stream
turbulent
Reynolds’ number greater than 2100 normally defines ______ flow but in highly controlled environment such as laboratories, laminar flow can be maintained up to values of Re as high as 50,000
turbulent
The flow is said to be uniform if, with steady flow for a given length, or reach, of a stream, the average velocity at every cross-section is the ______
same
