Why poiseuille equation not applied to turbulent flow?
Coz poiseuille eq is for poiseuille flow, which is a laminar flow, not turbulent flow. And it also need to be a fully developed , pressure driven flow.
What are examples of turbulent flow?
Smoke rising from a flame. At first the smoke rises with laminar flow before becoming turbulent just a few centimetres above the source.
What are examples of laminar and turbulent flow?
The Reynolds number, Re = VD/υ, can be used to measure the laminarity of flow. The smaller the Reynolds number, the more laminar the flow. Therefore, to achieve better laminar flow, V and D (velocity of fluid and diameter of pipe) should be small and υ, the kinematic viscosity of the fluid, should be large. Therefore, since pipe diameter and viscosity is fixed in this circumstance, the slower the velocity of the flow, the more laminar the flow. Open the faucet to a small degree and the flow will be laminar. Turn the facet open fully will (for some faucets) cause turbulent flow depending on the maximum velocity of water allowed by the faucet.
Is Bernoulli equation applicable for unsteady flow?
The equation assumes steady state or laminar flow and hence cannot be used for turbulent flows.
Give examples of objects are designed to reduce the amount turbulent flow of air or water over them.?
Objects designed to reduce turbulent flow include streamlined vehicles like airplanes and cars, which feature aerodynamic shapes that minimize drag. Boat hulls are also designed with smooth, elongated forms to promote laminar flow and reduce turbulence in water. Additionally, wind turbine blades are crafted to optimize airflow, enhancing efficiency by decreasing turbulence around the blades. These designs enhance performance and stability by ensuring smoother flow dynamics.
What is the equation for turbulent flow?
The equation for turbulent flow is described by the Navier-Stokes equations, which are a set of partial differential equations that describe how the velocity field of a fluid evolves over time. These equations take into account the fluid's viscosity, density, and the forces acting upon it. Turbulent flow is a complex, chaotic motion characterized by irregular fluctuations in velocity and pressure within the fluid.
What is turbulent flow?
Turbulent flow
What has the author H Snel written?
H. Snel has written: 'A semi-empirical model for the development of a round turbulent jet in a cross flow'
What are advantages of turbulent flow?
Turbulent flow allows for better mixing and heat transfer in fluids compared to laminar flow. It can also help prevent boundary layer separation and increase energy dissipation in the system. Additionally, turbulent flow enhances mass transport and can lead to more efficient industrial processes.
What has the author Julius E Harris written?
Julius E Harris has written: 'Computer program for solving laminar, transitional, or turbulent compressible boundary-layer equations for two-dimensional and axisymmetric flow' -- subject(s): Mathematical models, Turbulent boundary layer, Boundary layer, Laminar flow
How is turbulent flow different from laminar flow?

Which transports more sediment a laminar flow or a turbulent flow?
Turbulent flow transports more sediment than laminar flow due to the increased velocity and mixing of particles in turbulent flow. This helps to keep sediments suspended and advected downstream more effectively.
What are some examples of turbulent flow?
a block, Ping Pong ball or golf ball, kite, or simply running in the shallow pool. There are alot of things that have turbulent flow..... ping pong balls do not have turbulent flow nor does golf balls it has laminar flow things that have turbulent flow would be a bus, a hand out the window in a y axis or just a simple building or sky scrapper basically anything with a flat surface has turbulent flow
What measure will cause a laminar flow to become turbulent?
Increasing the velocity of the fluid will cause a laminar flow to become turbulent.
What are disadvantages and advantages of turbulent flow?
Advantage: objects in a turbulent flow experience less drag. Disadvantage: turbulent flows are unstable meaning velocity and pressures change rapidly. The objects in the flow have less stability. The flow also is more difficult to model then a laminar flow.
What are the Advantages and disadvantages for turbulent flow?
Advantages of turbulent flow include increased mixing and heat transfer rates, which can be beneficial in certain industrial processes. However, turbulent flow also requires higher energy inputs and can result in increased frictional losses compared to laminar flow. Additionally, it can be more challenging to predict and model turbulent flow behavior accurately.
