Solar Wind

1.3e36 particles per second, presumed monatomic hydrogen
- WP ref
- Area at 1 AU = 4π ( 150e9m )² = 2.8e23 m², hence flux = 1.3e36 H/s / 2.8e23 m² ≅ 5e12 H/(m²-s)
- Hydrogen mass 1.67e-27 kg, mass flux - 8e-15 kg/(m²-s)
slow wind 300–500 km/s, temperature ~1e5 K, twice as dense → 5e-15 kg/(m²-s)
- RMS isotropic thermal velocity ~50 km/s
  - RMS isotropic thermal velocity = sqrt( 3 k T / m ) ≈ 0.157 km/s * sqrt( T )
fast wind 750 km/s, temperature ~ 8e5 K, half as dense → 3e-15 kg/(m²-s)
- RMS isotropic thermal velocity ~140 km/s
