What is bulk flow engineering?
Bulk flow is the movement of a mass of fluid that is due to the presence of a pressure gradient. It is a common mode of transport of plant nutrients and water. The motion of the fluid is from an area of high pressure to an area of low pressure.
What is meant by bulk flow?
In general, bulk flow in plant biology typically refers to the movement of water from the soil up through the plant to the leaf tissue through xylem, but can also be applied to the transport of larger solutes (e.g. sucrose) through the phloem.

Why is it called bulk flow?
Bulk flow is the movement of substances in bulk or in masses down a pressure gradient. On the other hand, diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration along the concentration gradient.Nov 2, 2020

What is the difference between diffusion and bulk flow?
Diffusion occurs via the random motion of molecules; movement is from high to low concentration and depends upon the size of the molecule. Convection is the transport of a substance by bulk flow, where bulk flow is often the movement of fluid down a pressure gradient.Mar 6, 2019
Why does bulk flow happen?
Bulk flow, or volume flow, of air occurs wherever gradients of air pressure are found in the system. This obvious flow of air is produced by the bellows action of the thorax and is the characteristic function of larger animals that is called breathing.

How is diffusion and bulk flow connected to respiration?
The respiratory muscles cause convection, or bulk flow, of gas into the airways, while the cardiac system provides convection of blood to the tissues. Diffusion of gas occurs across both the alveolar and tissue capillary membranes.Jun 25, 2016
