How can I speed up my water?
Important Formulas – Boats and Streams
- Downstream. In water, the direction along the stream is called downstream.
- Upstream. In water, the direction against the stream is called upstream. Let the speed of a boat in still water be u km/hr and the speed of the stream be v km/hr, then. Speed downstream = (u + v) km/hr. Speed upstream = (u – v) km/hr.
What is the speed of the boat in still water it takes 2 hours?
2. What is the speed of the boat in still water? I. It takes 2 hours to cover the distance between A and B downstream….II.
| Speed of the boat = | 1 | (8 + 12) km/hr = 10 km/hr. |

How do you calculate the speed of a river?
The float method (also known as the cross-sectional method) is used to measure the flow rate for larger streams and rivers. It is found by multiplying a cross sectional area of the stream by the velocity of the water.
How do you calculate time in still water?
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)
What is the relation between distance and speed?
The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).
How can you measure the speed of a boat moving in water?
Pitometer logs (also known as pit logs) are devices used to measure a ship’s speed relative to the water. They are used on both surface ships and submarines. Data from the pitometer log is usually fed directly into the ship’s navigation system.
How does a Pitometer work?
A speedometer on a boat works by using a pitometer. The pitometer works by comparing how fast your boat is going against the speed of the water you’re travelling on. This works by measuring the speed of water coming into a tube compared to air pressure to give an estimated speed figure.
What is the speed of the boat?
The speed of a boat in still water is 11 km/hr. It can go 12 km upstream and return downstream to its original point in 2 hr 45 min.
How much is a speed boat?
A motorboat with outboard motors and no cabin, often called a speedboat or powerboat, also often designed for fishing, can cost anywhere from $20,000 if bought used to many hundreds of thousands of dollars for new models of the fastest speedboats on the water.
How do you solve a boat and stream problem easily?
Some Important Shortcuts:
- Suppose a man can row a boat at a speed of r km/hr in still water and covers the same distance up and down in a stream while a stream flows at a speed of s km/hr.
- A man rows downstream by covering a certain distance in p1 hours and returns the same distance upstream in p2 hours.
What is the difference between upstream and downstream in water?
Upstream means that the object is going opposite to the flow of the river. In this case you have to subtract the speed of the given object in still water from the speed of flow of the stream. Downstream means that the object is flowing along the river and in this case you have to add the speed.
What do you mean by upstream and downstream?
Upstream refers to the material inputs needed for production, while downstream is the opposite end, where products get produced and distributed.
What is downstream and upstream flow?
In short: “Upstream” is towards the source and “Downstream” is away from the source. Upstream is the direction toward the source and also against the current. “Gently Down the Stream” Alternatively, imagine that you have made it safely to the river bank and walked to bypass the waterfall.
What is upstream and downstream in rivers?
The term upriver (or upstream) refers to the direction towards the source of the river, i.e. against the direction of flow. Likewise, the term downriver (or downstream) describes the direction towards the mouth of the river, in which the current flows.
How does the water upstream affect the water downstream?
Upstream water treatment directly cuts off incoming pollutants, thereby presenting the smallest variation in its downstream effects on BOD levels. Treatment is advantageous when reliability of water quality is a primary concern. Dam discharge is a flexible tool, and may be used strategically during a low‐flow season.
How upstream affects downstream?
Typical examples might include polluted discharge in an upstream catchment that makes water downstream unusable; withdrawal of large amounts of water for irrigation upstream, leaving less water available downstream; as well as widespread land use change upstream which affects water availability and sediment loads …
What are downstream impacts?
These returns occur after the initial investments. As a result, they are referred to as downstream benefits. Similarly, investments can have downstream “costs” as well. At the same time, because the future is hard to predict, downstream effects are often unanticipated, setting off unintended costs and consequences.
What is downstream pollution?
Upstream is everything that went into that production of that product before it got to you, the consumer, including the extraction of natural resources, the manufacturing, the transportation, etc. Downstream is everything that happened to that product after you disposed of it. Air pollution from production.
What is upstream erosion?
Headward erosion is a fluvial process of erosion that lengthens a stream, a valley or a gully at its head and also enlarges its drainage basin. The stream erodes away at the rock and soil at its headwaters in the opposite direction that it flows.
What does Downcutting mean?
Downcutting, also called erosional downcutting, downward erosion or vertical erosion is a geological process by hydraulic action that deepens the channel of a stream or valley by removing material from the stream’s bed or the valley’s floor.
Why is upstream important?
In computer networking, upstream refers to the direction in which data can be transferred from the client to the server (uploading). Upstream speeds are also important to users of peer-to-peer software.
What does upstream mean?
in the direction opposite
