What is bulk movement of fluids?
Convection is the bulk movement of a fluid (gas or liquid) driven by pressure. Differential air pressures can drive gas movement through the tracheae and spiracles at much higher rates and over longer distances than diffusion.
What is meant by bulk transport?
(bʌlk ˈtrænspɔːt ) the transport of large quantities of goods or commodities in lorries, ships, or by rail.
Which transport called bulk transport?
The movement of macromolecules such as proteins or polysaccharides into or out of the cell is called bulk transport. There are two types of bulk transport, exocytosis and endocytosis, and both require the expenditure of energy (ATP). In exocytosis, materials are exported out of the cell via secretory vesicles.
What is bulk movement in physics?
Assertion : Mass or bulk flow is the movement of substance en masse from one point to another, as a result of pressure difference between the two points. Reason: It can be achieved only through positive hydrostatic pressure. JEE Main 2022 Question Paper Live Discussion.
What do you mean by bulk and mass flow?
Mass flow, also known as “mass transfer” and “bulk flow”, is the movement of fluids down a pressure or temperature gradient, particularly in the life sciences. As such, mass flow is a subject of study in both fluid dynamics and biology.
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.
How does mass transfer differ from bulk fluid motion?
In the process of bulk fluid flow, heat is transferred from a warmer to a cooler liquid. On the other hand, mass transfer occurs as a consequence of the. Bulk fluid flow enhances mass transfer, by removing the high concentration fluid near the surface and replacing it by the lower concentration fluid.
Which is an example of bulk flow?
Hint:Circulation of blood, water transport in xylem vessels and plant phloem tubes are the examples of mass or bulk flow systems.
Which represents an example of bulk flow?
Bulk flow is analogous to the flow of water through a pipe or the flow of blood through a blood vessel.
What is bulk flow?
Bulk flow is a process used by small lipid-insoluble proteins to cross the capillary wall. Capillary structure plays a large role in the rate of bulk flow, with continuous capillaries limiting flow and discontinuous capillaries facilitating the greatest amount of flow.Aug 13, 2020
Is blood flow an example of bulk flow?
Bulk flow is analogues to the flow of water through a pipe or flow of blood through a blood vessel. Unlike diffusion, bulk flow moves the entire solution, not just water or solutes. Hence, substances move in a mass during the bulk flow. Moreover, bulk flow is fast than diffusion.Nov 2, 2020
