What is K-factor and Y factor?

Y factor and K factor represent part constants used in formulas to calculate the developed length of flat sheet metal required to make a bend of a specific radius and angle in a design. Y factor and K factor are defined by the location of the sheet metal material's neutral bend line with respect to the thickness.

What is a K factor?

K Factor is a metric for app developers that reveals your app's virality, by measuring how many additional users each of your existing users brings along to the app. The term K Factor actually comes from the world of medicine, where it's used as a metric to measure how quickly a virus spreads.

What is the K factor value?

The K-factor comes from the ratio of the neutral radius divided by the thickness of the material on prepared charts and has a value between 0.3 and 0.5. The Y-factor looks at a similar value, but it takes the stresses inherent in the material into consideration, making it more accurate than the K-factor.

What is Y factor in bending?

What is Y factor? The Y-factor represents the part constant used in the formula to calculate the unfolded length of a sheet metal part bending with a specific radius and angle in the design. The Y-factor is defined by the position of the neutral bending line (in relation to the thickness) of the sheet metal part.

What is K in sheet metal?

In sheet metal, the K-factor is the ratio of the neutral axis to the material thickness. When a piece of metal is being formed, the inner portion of the bend compresses while the outer portion expands (see Figure 1).

Sheet Metal Basics: What is the K Factor?

What is K-factor in calibration?

K-Factors are calibration values (pulses per unit of volume) used to convert flow sensor output frequencies to flow rates. This calculation tool helps you to determine the correct K-Factor for your flow sensor.

What is K-factor in transformer?

K-factor is a weighting of the harmonic load currents according to their effects on transformer heating, as derived from ANSI/IEEE C57. 110. The higher the K-factor, the greater the harmonic heating effects. There are many different loads such as computers, solid state devices and motors which cause a non linear load.

What is K-factor in flow meter?

For aircraft fuel flow meters, K-factor refers to the number of pulses expected for every one volumetric unit of fluid passing through a given flow meter, and is usually encountered when dealing with pulse signals.

What is K-factor in air flow?

The K factor is the point at which the size of the box, shown in inches, converges with the maximum airflow at 1"w.g. velocity pressure (on the far right).

What is soil K-factor?

The K Factor is an index which quantifies the relative susceptibility of the soil to sheet and rill erosion. • K Factor is used in the RUSLE2 soil loss prediction equation. Values range from 0.02 for the least erodible soils to 0.64 for the most erodible.

What is K-factor in oil and gas?

The k factor is a calculation that shows how quickly a home is consuming the fuel it uses to produce heat. The k-factor calculation can be used in homes that use all types of combustible fuel, from natural gas to propane to heating oil. A home's k factor represents the number of gallons of fuel burned per degree day.

Why do we use K-factor?

The K-Factor is used to calculate flat patterns because it is directly related to how much material is stretched during the bend. It's used to determine Bend Allowances and Bend Deductions ahead of the first piece.

What is K-factor analysis?

key factor analysis A technique for predicting fluctuations in population size based on identifying the relative contributions made to it by the key factors of births, deaths, immigration, and emigration.

What is virality and K-factor?

K-factor is a measure of virality of an app (or a website, or a customer base). Put simply, the K-factor is the total number of new activated users generated by a single existing activated user.

What is K in flow rate?

The K-factor is the frequency divided by the flow rate => [1/s] / [g/s] = 1/g. Knowing the K-factor for each calibration point, the factory determines the best fitting K-factor for that particular flowmeter. Calibration points are determined by averaging all K-factors.

What is K-factor of water?

The “K-Factor” of a water meter is the manufacturer's way of describing liquid flow through their meter. A K-factor of “100” means that there are 100 “pulses” produced for each gallon of water.

What is the K-factor unit?

K-factor helps to calculate the discharge rate from fire sprinkler heads. It's calculated in imperial units for the United States by using the flow in gallons per minute (gpm) and the pressure in PSI. Metric calculations use the flow in liters per minute and pressure in bar.

What is K rating?

K: Content suitable for most ages, usually those aged five and older. It should be free of coarse language, violence, and adult themes. Equivalent to G. K+: Some content may not be suitable for young children, usually those below nine years of age.

In which one is K in transformer?

Transformation Ratio (K)

The transformation ratio for voltage is defined as the ratio of secondary voltage to the primary voltage of a transformer. It is denoted by K.

What is K 4 rated transformer?

The K4 Transformer is used in applications in which a major portion of the load is non-linear devices, and the 24 hour average load duty cycle is 80% or higher. The K13 rated Transformer is used where the majority of the load is non-linear, and the 24 hour average load duty cycle is 95% or higher.

How do you adjust K-factor for flow?

If the flow rate was given in units per minute the totalizer K-factor (for whole units) is obtained by multiplying the rate K-factor by 60. If the flow rate was given in units per hour the totalizer K-factor (for whole units) is obtained by multiplying the rate K-factor by 3600.

What is meter factor?

Meter factor means a dimensionless term obtained by dividing the gross standard volume or mass of liquid passed through the meter (as measured by a prover during proving) by the corresponding meter indicated volume at standard conditions.

What is centrifugation K-factor?

The k-factor represents the pelleting efficiency of a centrifugation system at maximum rotational speed. The factor is a measure of the sedimentation distance in a test tube; it depends on the difference between the longest and the shortest distance between the sample and rotor axis.

How do you calculate K-factor growth?
