What is upstream and downstream water?

What is upstream and downstream water?

To help you remember which way is upstream on a river, if water comes from, for example, the mountains and flows in a river to the sea, water near the mountains (or source) is upstream, and water nearer the sea is downstream.

What does upstream process mean?

Upstream Processing refers to the first step in which biomolecules are grown, usually by bacterial or mammalian cell lines, in bioreactors. When they reach the desired density (for batch and fed batch cultures) they are harvested and moved to the downstream section of the bioprocess.

What does downstream mean in oil and gas?

Downstream Oil and Gas Production The closer an oil and gas company is to supplying consumers with petroleum products, the further downstream it is said to be in the industry. Downstream operations are oil and gas processes that occur after the production phase to the point of sale.

What is downstream and upstream in maths?

Downstream/Upstream: In water, the direction along the stream is called downstream. If the speed of a boat in still water is u km/hr and the speed of the stream is v km/hr, then: Speed downstream = (u + v) km/hr. Speed upstream = (u – v) km/hr.

What is boat and stream?

1) Still water: The water of a river or any other water body which is not flowing is known as still water. 2) Stream: It is the flowing water of a river which is moving at a certain speed. 4) Downstream: The boat or a swimmer moving along the stream is known as moving downstream i.e. along the flow of water.

Which is downstream process?

Downstream processing refers to the recovery and the purification of biosynthetic products, particularly pharmaceuticals, from natural sources such as animal or plant tissue or fermentation broth, including the recycling of salvageable components and the proper treatment and disposal of waste.

What is downstream demand?

In this context, many researchers have studied a phenomenon called Downstream Demand Inference (DDI), which presents an effective demand management strategy to deal with forecast problems. DDI allows the upstream actor to infer the demand received by the downstream actor without the need of information sharing.

What is upstream in a river?

English Language Learners Definition of upstream : in the direction opposite to the flow in a stream, river, etc. : toward the source of a stream, river, etc.

What is upstream in oil and gas?

Upstream refers to points in production that originate early on in the processes. Also called exploration and production (E&P), upstream is farthest from the end-user consumer in the oil & gas supply chain. Upstream activities include exploration, drilling, and extraction.

What is upstream and downstream in river formula?

Questions on Average Speed – With the speed of the boat upstream and downstream given in the question, the average speed of the boat may be asked. Questions Based on Distance – The distance travelled by boat upstream or downstream may be asked.

What is upstream and downstream in manufacturing?

Upstream processes are those in which biological materials are either obtained from an outside source or inoculated and grown in culture, under controlled conditions, to manufacture certain types of products. Downstream processes are those in which the products are harvested, tested, purified and packaged.

What is upstream and downstream flow in piping?

Downstream is the flow of fluid towards the end point of a pipe you are considering while upstream is away from the the end point i.e. going upward.

What is the difference between upstream and downstream flow?

Upstream refers to the material inputs needed for production, while downstream is the opposite end, where products get produced and distributed.

What is meant by upstream process?

Key Takeaways Upstream refers to points in production that originate early on in the processes. Also called exploration and production (E&P), upstream is farthest from the end-user consumer in the oil & gas supply chain. Upstream activities include exploration, drilling, and extraction.

What is the opposite of upstream?

Upstream is the opposite of downstream, which refers to data transferred from a server to a local machine. When referring to Internet nodes, a node that is closer to the Internet backbone is said to be upstream of a node than that is farther away from the backbone.

What is the definition of upstream?

Definition of upstream. 1 : in the direction opposite to the flow of a stream. 2 : in or to a position within the production stream closer to manufacturing processes make most of its money upstream, selling cheap crude … to refineries— John Quirt.
