What is the K-factor of a sprinkler?

1.1. K-factor is a mathematical constant established by the sprinkler manufacturer that relates the flow of water that is discharged from the sprinkler at a given pressure.

How do you convert K-factor?

To convert from an Imperial sprinkler K factor to a Metric sprinkler K factor multiply by 14.4 approximately. For standard type sprinkler heads the many design standards specify K-factors and minimum pressure requirements, which can be used for different Hazard classifications and design densities.

What is K-factor for spray nozzle?

From Wikipedia, the free encyclopedia. In fire protection engineering, the K-factor formula is used to calculate the discharge rate from a nozzle. Spray Nozzles can be fire sprinklers or water mist nozzles, hose reel nozzles, water monitors and deluge fire system nozzles.

How do you calculate sprinkler area?

In short, to determine the minimum flow from a sprinkler in multiplying the area by the required density, is the actual area of the room used (13′-0″ x 13′-0″ = 169 sqft) or is it computed the same as the maximum area of coverage for a sprinkler by doubling the furthest distance from adjacent walls [(7′-0″ x 2) x (7′-0 …

How are sprinkler zones calculated?

Calculating Zones Each zone should include plants with the same watering needs, or an area of the lawn. Then, add up the necessary flow rate in GPM of all the sprinkler heads, divided by the GPM of your water supply. The resulting number will equal how many zones you need.

What is the K factor formula?

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.

What is the standard K factor?

The K-factor is usually somewhere between 0.3 and 0.5.

What is K-factor referral?

K-factor in marketing is used to describe the virality rate of apps / websites through referral programs, or “hidden” virality, which is word-of-mouth. In other words, the higher your K-factor is, the more people are spreading the good word about your app.

What is K-factor of flow device?

Meter K-Factor is defined as the number of pulses per unit mass or volume at a particular flow rate. Every meter in each turbine contains a K-Factor or a ratio of the pulses per unit of flow. Every time a turbine rotates within a flow rate, the turbine blade passes a face of magnet that creates an electronic pulse.

What is the K factor on a sprinkler head?

The numerical designation given to represent the hydraulic characteristic of a sprinkler head is called the k-factor. The k-factor for different sprinkler heads may range from k= 5.6 (standard ½” orifice) to k=14.0 for ESFR sprinklers.

What is the formula for k factor?

If R factor is unknown, the formula to calculate the K factor of insulation is: K factor = BTU-in / hr – ft 2 – °F. or. British Thermal Unit-Inch Per Square Foot Per Hour Per Fahrenheit Degree. If R factor is know, this easier formula can be used to calculate the K factor: K factor = inches of thickness / R Factor.

What are k factors?

Calculating the K-Factor. Since the K-Factor is based on the property of the metal and its thickness there is no simple way to calculate it ahead of the first bend.

  • K-Factor Chart.
  • The K-Factor of a 180° Bend (Hem) The K-Factor for a 180° bend is going to be meaningless because it’s tied to the Outside Setback which approaches infinity as the
  • What is flow K factor?

    K-factor (aeronautics) 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.
