The important characteristics about Jet stream are- Jet streams are narrow, fast-flowing, meandering air currents in the atmospheres of some planets, including Earth. The strongest jet streams are subtropical jets at the higher altitude and somewhat weaker are polar jets.

The correct answer is option(1).i.e.Only 1.

  • Jet streams are fast-flowing, narrow, meandering air currents in the atmospheres of some planets, including Earth.
  • The strongest jet streams are polar jets at the higher altitude and somewhat weaker are subtropical jets. 
  • Jet streams: 
    • Jet streams are narrow, fast-flowing, meandering air currents in the atmospheres of some planets, including Earth.
    • The main jet streams are located on Earth near the altitude of the tropopause and are westerly winds.
    • Their paths generally have a meandering shape​. 
    • The Southern Hemisphere & Northern Hemisphere and each have a subtropical jet & a polar jet.
  • Product of two factors: 
    • The jet stream is basically is the product of two factors: 
  • Solar Radiation:
    • The heating of the atmosphere by only by solar energy that produces the large-scale Hadley,  Ferrel, Polar, circulation cells.
  • Coriolis force: 
    • The second act of the Coriolis force which enacting on those moving masses.

The fresh feed to an ammonia synthesis reactor contains nitrogen, hydrogen and 2.0 mole per cent inerts. The molar ratio of H2:N2 is 3:1. The product stream consists of pure ammonia. Since conversion in the reactor is only 15%, a recycle stream is used and in order to avoid build-up of inerts, a purge stream is withdrawn. The rate of purge stream is adjusted to keep inert concentration in the recycle stream at 8 mole per cent. For a fresh feed rate of 100 moles/hr. Note that recycle stream contains only nitrogen, hydrogen and inerts. The N2:H2 ratio of 1:3 is maintained in every process stream, and calculate the moles of nitrogen entering the reactor and in the recycle stream?
