Velocity is a speed and its direction. Speed is the quotient of change in distance (D) divided by change in time (T). Therefore calculating speed is dependent on the two variables of D and T, as well as the direction in which the position has changed. In SI unites the measure of the magnitude of velocity uses meters (m) per second(s).

How do you calculate the flue gas velocity in airpreheater?
To calculate the flue gas velocity in an air preheater, you would need to know the volumetric flow rate of the flue gas passing through the preheater and the cross-sectional area of the preheater. You can then use the formula: Velocity = Volumetric flow rate / Cross-sectional area of preheater. This calculation will give you the velocity at which the flue gas is moving through the air preheater.
To describe velocity you need to know?
Speed is a function of distance and time. For example we refer to 'miles per hour' or 'kilometres per hour' or 'feet per second'' or metres per minute' etc. To determine speed, you need to know the distance travelled and the time it took to travel that distance.
How do I calculate the velocity of an object which hits a stationary object if I know the mass of both objects and the distance the stationary object was moved what else must I know to calculate?
In addition to the mass of both objects and the distance the stationary object was moved, you need to know the coefficient of restitution or the type of collision (elastic or inelastic). This information will help you determine how much kinetic energy was transferred during the collision and allow you to calculate the velocity of the moving object before and after the collision.
Do you need to know atomic weight to calculate molarity?
No, you do not need to know the atomic weight to calculate molarity. Molarity is calculated by dividing the moles of solute by the volume of solution in liters. Knowing the atomic weight can help determine the number of moles in a given mass of solute, but it is not required to calculate molarity.
How do you calculate air flow rate through a tapered cylinder?
Using conservation of mass: mass flow rate = ρ * V * A where ρ= density, V= velocity, and A= cross sectional area therefore since massin = massout therefore: (ρ*V*A)in = (ρ*V*A)out
What two pieces of information are required to calculate average velocity?
To calculate average velocity, you need the total displacement of the object and the total time it took to cover that displacement.
What To calculate an object's acceleration you need to know?
To calculate an object's acceleration, you need to know its initial and final velocity, as well as the time taken to change velocity. Acceleration is calculated using the formula acceleration = (final velocity - initial velocity) / time.
What two measurements must be known to calculate velocity?
To calculate velocity, you need to know both the object's displacement (change in position) and the time it takes for that displacement to occur. Velocity is the rate of change of position with respect to time.
What variables do you use to calculate acceleration?
To calculate acceleration, you need to know the change in velocity (final velocity - initial velocity) and the time taken for that change to occur. Acceleration = (Change in velocity) / (Time taken).
What two values do you need to know to calculate the momentum of an object?
To calculate the momentum of an object, you need to know its mass and velocity. The momentum of an object is the product of its mass and velocity, which indicates how difficult it is to stop the object when it's in motion.
How do you calculate time to accelerate?
You can calculate the time to accelerate using the formula, time = (final velocity - initial velocity) / acceleration. To do this, you need to know the initial velocity, final velocity, and acceleration of the object. Plug these values into the formula to find the time it takes to accelerate.
What must you know about an object that is moving in a straight line to calculate its acceleration?
To calculate the acceleration of an object moving in a straight line, you need to know the initial velocity, final velocity, and the time it takes for the change in velocity to occur. Acceleration is calculated as the change in velocity over time.
What information is needed to determine the average velocity of a marble?
All you need to know is the distance the marble travelled and how long it took to travel that distance. For example, if a marble travels 30 cm in 5 seconds then its average velocity would be 30 / 5 cm / sec = 6 cm / sec.
How do you find the average velocity pressure?
To find the average velocity pressure, you would need to calculate the total velocity pressure and divide it by the number of measurements taken. This would give you the average velocity pressure over the measurement period.
What information do you need to calculate velocity?
To calculate velocity, you need the displacement of an object (the change in position) and the time it took to make that displacement. Velocity is determined by dividing the displacement by the time taken to achieve that displacement.
Anya knows the velocity of an object. What else does she need to know in order to find the objects momentum?
The mass of the object.
How can you get average velocity?
You can calculate average speed by dividing the total distance travelled by the total time of travel. To go from speed to velocity, you would also need to determine the vector (direction of travel).
