Neutron Flux Calculator
☢ Nuclear & Decay. Use the Neutron flux formula to find flux φ, neutron density, speed: pick the value you want, type the others, and the answer updates as you go.
Flux Φ2.2 × 10¹⁷ 1/(m²·s)
Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.
What each letter means
| Quantity | Unit |
|---|---|
| Flux Φ | 1/(m²·s) |
| Neutron density | 1/m³ |
| Speed | m/s |
Worked example
Find the flux φ when Neutron density = 1 × 10¹⁴ 1/m³, Speed = 2200 m/s.
Using = n v: Flux Φ = 2.2 × 10¹⁷ 1/(m²·s).
Frequently asked questions
What is the formula for Neutron flux?
= n v.
What do the letters stand for, and what units are used?
Flux Φ in 1/(m²·s), Neutron density in 1/m³, Speed in m/s.
How do you calculate flux φ?
Put the values into = n v. For example, with Neutron density = 1 × 10¹⁴ 1/m³, Speed = 2200 m/s, flux φ = 2.2 × 10¹⁷ 1/(m²·s).
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (flux φ, neutron density, speed) and fill in the others: it rearranges the formula for you.
