Velocity

result of valve opening 55° and 1 m/s velocity. CHAPTER 4 RESULTS AND DISCUSSION A numerical analysis of a butterfly valve using computational fluid dynamics software FLUENT has been used to analysis the fluid field and study the various parameter like flow velocity, Static pressure and turbulence intensity for a various valve closing angle of 0, 20, 30,55,75,90 degree and different inlet velocity and the values become0.5, 1, 1.5, and 2 m/s. CASE 1: Velocity 0.5 m/s for valve opening angle…

set of velocity and height from the ball. The height of the ball when it leaves the horizontal projectile is at 93.5cm or .935m. The velocity of the ball was .0674 seconds in the range of .1 meter. Creating a total velocity of 1.484m/s. To calculate the hang-time the formula: y= -4.9t^2 was used. The hang time is used to figure out how long the ball will be in the air for. After you find the answer, the time is then multiplied by the velocity to get the range. The horizontal velocity…

Is velocity the reason why a curveball drops? Statistics show that the velocity of a ball does not cause the curveball to drop. There are other variables involved like air pressure, rotation of the ball, and aerodynamics. These are very important factors when a baseball is thrown. A Big part of velocity is the air pressure, this is because of a separate topic called the Magnus Effect - a force exerted on a rapidly spinning cylinder or sphere moving through air in a direction at an angle to the…

similar to velocity, it was greatest at the top of the track and was least in the middle of the loop or in the dip of the track. The kinetic energy was actually least at the top of the track and greatest in the middle of the loop or in the dip of the track.…

graph as well as a velocity versus time graph. In order to have the data fit the situation of the bouncing ball, we zeroed the sensor so the ground was considered as zero and above the ground was considered positive. These setting will help us get the best results. The position versus time and the velocity versus time graphs are shown below: In the position v. time…

there must be a change in the velocity…

on the ice the whole time during my shot, changing just the position of the puck, my slapshot took 4 seconds to cross the far goal line, making my slapshot move at a velocity of 15.24 meters per second. This calculation was done by divided the total displacement by the total time, 60.98 meters divided by 4 seconds. Finding the velocity of the puck relates to what we are doing in class, as we are talking about…

(4) Maximum space velocity is a specific manufacturer metric which is the maximum gas flow velocity in the substrate and converted into the peak localized space velocity: SV = 3600("ρgas" /"ρatmos" )( (Vmax )/L) (5) Where; gas is the gas density in kg/m3; atmos is the gas density at 25C and at 101325 Pa; Vmax the maximum gas velocity in…

graph to another. Since the slope is constantly changing, the velocity is non-constant. Also, as the graph lies above the x-axis and its slope is increasing, the velocity of the object is also increasing (speeding up) in a positive left direction. Segment B (Position-Time on Flat Surface): The graph is a straight line, which represents constant velocity. The slope is negative, which indicates that the object is moving at a constant velocity left. Including the part in which the car slows down…

later, its velocity is 19.6 m/s. After falling for 10 seconds, its velocity is 98 m/s or about 219 miles per hour! • A force is a push or a pull. • A force can act through contact -– Spring, rope, chain, friction, etc. • A force can act at a distance. -– Gravity, magnetism, electrical Galileo observed that the final velocity of an object starting from rest and accelerating at a constant rate equals the product of the acceleration and the elapsed time. If it has an initial velocity, the final…
