## Related Questions To find the velocity ratio of a pulley, you must first find the effort and load distances. then you divide the two and there you have you VR (velocity ratio). The ratio for a simple pulley (not a pulley block), using an inelastic string, is 1. to avoid the slip , increase the velocity ratio and increase belt and pulley life... thanku..:) it is the ratio of the velocity of the point of application of effort to the velocity of the load  Number of teeth on driven gear divided by number of teeth on driver gear No. The velocity ratio remains constant but the friction absorbs power. velocity ratio/mechanical advantage x 100/1 all in percentage Drive Pulley = pulley on motor Driven Pulley = pulley on blower First determine your Ratio - divide large pulley size by small pulley size this will give you gear ratio, Example 2" drive pulley and a 4" Driven Pulley = 2:1 gear ratio If you know your motor shaft RPM divide that number by the ratio to get the RPM of the driven pulley, if your shaft rpm is 1800 rpm you would divide 1800 by 2 which would = 900 rpm on your driven pulley if your drive pulley is larger than than your driven pulley you multiply the rpm by the ratio example 1800 rpm x 2 = 3600 rpm  Assuming that you have high frequency velocity measurements it's relatively simple. It is simply the ratio of u' to U - meaning the average fluctuating component of the velocity divided by the mean velocity. I = u'/U :)  the formula t calculate velocity is:velocity (v)=distance(d)/time(t) the speed something moves in is velocity Load "L" is attached to the movable pulley. A rope is fixed at a point in ceiling that passes through the movable pulley. In order to lift the load "L" by "X" meters, the effort "E" needs to travel the distance of 2X meters. (The entire rope needs to be pulled by "E" for a distance of 2X.) Now, Velocity Ratio equals (Distance traveled by "E") divided by (Distance traveled by "L") So it becomes : 2X/X. This equals to 2 Since it is a ratio. it has no units of measurement. -Kiran Karnik The angular velocity of a pulley turning 1800 rpm is 60 pi radians per second.  For an object moving at a variable velocity you:calculate the square of the velocityfind its mean valuecalculate its square root.If the velocity is constant then the RMS velocity has the same value. We can calculate from the slope by te formula velocity = displacement / time They both characterize the frictionless mechanical advantage of a machine The relationship between mechanical advantage, velocity ratio &amp; efficiency is:- efficiency=Mechanical Advantage/Velocity Ratio how do we calculate credit loss ratio in banks financials acceleration=ratio of change in velocity in a specific direction to time. speed=ratio of distance to time. Speed and Velocity are two different things . Velocity- "the rate at which an object changes its position." Speed- "How fast an object is moving". To calculate speed and velocity, you first need to calculate distance and time. Velocity is considered to be a more logical term No. It can be but need not be. For example, you might calculate the ratio of today's temperature in Celsius and in Fahrenheit and calculate the ratio. That is not a rate.
