## How is upstream and downstream speed calculated?

Upstream and Downstream – Formula

- Upstream = (u−v) km/hr, where “u” is the speed of the boat in still water and “v” is the speed of the stream.
- Downstream = (u+v)Km/hr, where “u” is the speed of the boat in still water and “v” is the speed of the stream.
- Speed of Boat in Still Water = ½ (Downstream Speed + Upstream Speed)

## Which is faster downstream or upstream?

In the downstream motion, the boat and the water move in the same direction and thus the speed is more than what it will be when the two are moving opposite to each other. In other words, the upstream motion is slower. This is the velocity of the boat with respect to water or the speed of the boat in still water.

**What will be the speed of the boat in downstream cases?**

So in case of downstream the speeds will be added, while in case of upstream the speeds will be subtracted . The speed of boat downstream is equal to the sum of the speed of the boat in still water and speed of the stream .

### Is still water upstream or downstream?

Upstream- When the boat is flowing in the opposite direction of the stream, it is called Upstream. Downstream- When the boat is flowing in the same direction as the stream, it is called Downstream. Still Water- When the water is stationary i.e. not flowing then the speed of water is zero.

### What is downstream and upstream?

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

**What is a good downstream rate?**

Downstream speeds can range from 56 kilobits per second (Kbps) for dial up to 50 megabits per second (Mbps) for the fastest fiber-optic network connections offered by some Internet service providers. The average DSL connection is from 1 to 10 Mbps. Cable modems average 10 to 20 Mbps.

## What is a downstream frequency?

The forward (or downstream) path is from the cable operator’s headend to the subscriber and is generally from 54 MHz to as high as 1000 MHz. This frequency range is typically from 5 MHz to 42 MHz.

## Why do boats sail faster downstream?

A keel works only if the motion of the boat is not exactly in the direction in which it’s pointed. The boat must be moving somewhat sideways. Just as for the sails in the wind, that causes the water on the “high” (more downstream) side of the keel to move faster and create a lower pressure.

**Is downstream and still water same?**

Important Terms for Boats and Streams Formula Stream- The water that is moving in the river is called a stream. Downstream- When the boat is flowing in the same direction as the stream, it is called Downstream. Still Water- When the water is stationary i.e. not flowing then the speed of water is zero.

### Is downstream with the current?

The definition of downstream is in the same direction that the current of water flows. When a piece of driftwood is moving left and the current of the water is moving left, this is an example of a time when the driftwood is moving downstream.

### What is the difference between upstream midstream and downstream?

‘Upstream’ is about extracting oil and natural gas from the ground; ‘midstream’ is about safely moving them thousands of miles; and ‘downstream’ is converting these resources into the fuels and finished products we all depend on.

**What is the formula for upstream and downstream?**

According to the formula, Speed of the stream = ½ (Downstream Speed – Upstream Speed) Speed of the stream = ½ (26-16) = ½ × 10 = 5 km/hr Q 4.

## How to calculate the speed of a boat upstream?

Upstream = (u−v) km/hr, where “u” is the speed of the boat in still water and “v” is the speed of the stream; Downstream = (u+v)Km/hr, where “u” is the speed of the boat in still water and “v” is the speed of the stream; Speed of Boat in Still Water = ½ (Downstream Speed + Upstream Speed)

## How to calculate the speed of a stream?

Since ‘b’ is the speed of the boat in still water, which is = 9 km/hr. Therefore, we have 3r = – (9) or r = -3 km/hr. Neglecting the negative sign as this is the speed of the river, we have the speed of the stream = C) 3 km/hr.

**Which is an example of a downstream problem?**

One of them is what we call the downstream problems. In the stream boat problems, a boat goes upstream or downstream. You will have to answer the questions about the speed of the boat and the speed of the river. Here we will see many such examples and try to get as familiar with these concepts as possible.
