What causes velocity to decrease?
Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity.
How do you decrease velocity?
Commonly used engineering devices to reduce runoff velocity include terraces and waterways. (i) Terraces: Long slopes are broken with earthworks installed at right angles to the steepest slope to intercept the surface runoff (Plate 34).
Which liquid has more velocity?
Note that speed is a scalar quantity. Velocity is vector quantity with direction….Speed of sound in some common fluids – like water, glycerol, kerosene …
| Liquid | Speed of Sound1) (m/s) |
|---|---|
| Benzene (25oC) | 1298 |
| Bromobenzene (20oC) | 1169 |
| Bismuth (280oC) | 1651 |
| Butane (-0.5oC) | 1038 |
What affects velocity?
The factors affecting the terminal velocity of an object include:
- its mass.
- its surface area.
- the acceleration due to gravity , g.
How can you increase the velocity of water?
Flow rate of a fluid in a pipeline is velocity times the cross sectional area. So if you want to keep the flow rate constant and increase the velocity, you will have to decrease the criss sectional area of the pipe i.e. use the pipe with a smaller diameter.
What is the relation between pressure and velocity?
Pressure and velocity are inversely proportional to each other. If pressure increases, the velocity decreases to keep the algebraic sum of potential energy, kinetic energy, and pressure constant.
How do you calculate water velocity?
Alternatively, if the flow rate is measured in gallons per minute, the following formula can be used to calculate water velocity. Thus, the velocity v in feet per second is equal to 0.408 times the flow rate Q in gallons per minute divided by the pipe diameter D in inches squared.
How do you convert pressure to velocity?
V = 4005 x square root (delta P)
- Delta P = ( pressure change in inches WC)
- V = Velocity(ft/min)
