What is the unit of K factor?

What is the unit of K factor?

K-Factors have also been calculated and published in US units of PSI and GPM. Within the United States, only US measurements (PSI, and US-Gallons per minute) are used.

What is K value for sprinkler?

The k-factor for a fire sprinkler is the discharge coefficient, or in normal human terms just relates to the amount of water that is permitted through the sprinkler. The k-factor is dependent upon the orifice diameter of the sprinkler – a low k-factor (such as K2. 0) permit much more water to flow through.

What is a K factor?

K factor is a ratio between the distance from the neutral bend line to the inside bend radius and the material thickness. K factor uses the formula K factor = δ/T. Y factor uses the formula Y factor = K factor * (Π/2). The default value for Y factor is 0.50. Developed length of material and Y factor and K factor.

How do you calculate K factor flow?

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.

What is flow K-factor?

From Wikipedia, the free encyclopedia. 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 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.

How do you select K-factor for sprinklers?

K-factors can be determined by using the following equation: K = Q/P1/2, where K is represented by gallons per minute, or gpm/psi1/2, Q is flow rate in gpm and P is pressure in psi, or pounds of force.

How do you calculate K-factor for sprinklers?

K-Factor formula for fire sprinklers

1. Q = AV.
2. Q = A√(2gh)
3. q = kp0.5
4. k = q / p0.5
5. p = ( q / k )2
6. for metric calculations: p = pressure in Bar. q = flow in litre per minute. k = discharge constant Lpm/Bar0.5
7. and for imperial calculation: p = pressure in psi. q = flow in gpm. k = discharge constant gpm/psi0.5

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.

How is Watson characterization factor calculated?

Depending on the value of the Watson characterization factor, crude oils are classified as paraffinic (Kw = 11-12.9), naphthenic (Kw =10-11), or aromatic (Kw <10). where V(100°F) is the viscosity in SUS and SG is the specific gravity at 15.6°C (60°F)….Characterization Factors.
