## Why is laminar flow important

Answered By: Hugh Hill Date: created: Jul 27 2021

Laminar flow is the opposite of turbulent flow. … It is the smooth flow of a fluid over a surface. Though a boundary layer of air “sticks” to a wing, the air overtop should be moving quickly and smoothly to reduce friction drag.

## Which are dimensionless numbers

Answered By: Fred Rogers Date: created: Oct 15 2021

Dimensionless numbers in many fields of engineering are collections of variables that provide order-of-magnitude estimates about the behavior of a system (Table 1.5). They are often derived by combining coefficients from differential equations and are oftentimes a ratio between two physical quantities.

## Is force a dimensionless quantity

Answered By: Elijah Morgan Date: created: Jul 19 2021

The ratio of the internal forces to the external forces will depend upon its speed, and the viscosity of the fluid, and the size of the body. … But the ratio of the internal to the viscous forces is dimensionless, so it must depend on some combination of the viscosity, speed V and linear size l that is dimensionless.

## What are characteristics of laminar flow

Answered By: Benjamin Robinson Date: created: Dec 07 2021

In fluid dynamics, laminar flow is characterized by fluid particles following smooth paths in layers, with each layer moving smoothly past the adjacent layers with little or no mixing. At low velocities, the fluid tends to flow without lateral mixing, and adjacent layers slide past one another like playing cards.

Asked By: Joshua Cook Date: created: Nov 08 2021

## Which property of fluid is dimensionless

Answered By: Jackson Bennett Date: created: Nov 09 2021

Inertia force always exists if there is any mass in motion. Dividing this inertia force with other forces like viscous force, gravity force, surface tension, elastic force, or pressure force, gives us the dimensionless numbers.
