Does pressure affect mass flow rate?
Doubling the line pressure halves the volumetric flow rate, and decreasing line pressure increases the volumetric flow rate. However, the number of molecules of air that flow (mass flow rate) does not change.
What is the relation between pressure and area?
The relation between pressure and area is that pressure and area are inversely proportional to each other. That is when area decreases pressure exerted on that area increases. When area increases pressure exerted on that area decreases.
What are the different types of flow meters?

- Custody transfer of natural gas metering.
- Steam measurement.
- Flow of liquid suspensions.
- General water applications.
- Liquid chemicals & pharmaceuticals.
What is the principle of vortex flow meter?
Vortex flow meters measure fluid velocity using a principle of operation referred to as the von Kármán effect, which states that when flow passes by a bluff body, a repeating pattern of swirling vortices is generated.
What is K factor in vortex flow meter?
D = Inside diameter of the meter. K-Factor. The vortex K-Factor is the proportionality constant that is used to relate the measured frequency to a volumetric flow rate. The K-Factor is determined using a flow lab calibration.
What is K factor in fuel flow?
The K-factor is a constant, referring to the number of measurable pulses required for a given volume of fuel to pass through the point where flow is being measured. Sensors measuring these pulses send the signal to an onboard chip that converts the pulses into volume, using the K-factor.
What K factor means?
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 K factor for 43 degree bend?
K-Factor Chart
| Radius | Soft / Aluminum | Medium / Steel |
|---|---|---|
| 0 – Mt. | .33 | .38 |
| Mt. – 3*Mt. | .40 | .43 |
| 3*Mt. – >3*Mt. | .50 | .50 |
| Bottom Bending | ||
Is a higher or lower K factor better?
What is the K Factor of Insulation? The K factor of insulation represents the material’s thermal conductivity or ability to conduct heat. Usually, insulation materials have a K Factor of less than one. The lower the K factor, the better the insulation.
