Match the following flow types with their descriptions:
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:
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:
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
