Ion and Hall Thruster Plumes 427 d = b db d sin d = d d . d Compute the differential and total cross sections for (i) collisions between hard spheres of diameter d and (ii) a repulsive force field between particles that varies as k/ r2 (k is a constant). 4. The most general elastic collision process between two particles of unequal masses, m1 and m2, velocity vectors before the collision, u1 and u2, and after the collision, u1' and u2', can be represented by the geometrical construction in Fig. 8-21 using the following definitions: Relative velocities: U = u1–u2, U' = u1'–u2' Center-of-mass (CM) velocity: uc = (m1u1 + m2u2)/(m1 + m2) Reduced mass: M = m1m2/(m1 + m2) a. In the case of equal masses, m1 = m2 = m, and one stationary particle, u2 = 0, draw the new geometrical construction. What is the relationship between the scattering angle in the CM frame, , and the scattering angle in the laboratory frame, ? b. Convert the CM differential cross section, d /d CM, into the laboratory frame of reference, d /d L. m1u’1 m1u1 β m2u’2 MU’ MU θ m2u2 m1u1 + m2u2 = (m1 + m2) uc Fig. 8-21.

Infinity Supercritical CO2 10 Liter Extractor Design and Worldwide Rights: The Infinity Supercritical 10L CO2 extractor is for botanical oil extraction, which is rich in terpenes and can produce shelf ready full spectrum oil. With over 5 years of development, this industry leader mature extractor machine has been sold since 2015 and is part of many profitable businesses. The process can also be used for electrowinning, e-waste recycling, and lithium battery recycling, gold mining electronic wastes, precious metals. CO2 can also be used in a reverse fuel cell with nafion to make a gas-to-liquids fuel, such as methanol, ethanol and butanol or ethylene. Supercritical CO2 has also been used for treating nafion to make it more effective catalyst. This NFT is for the purchase of worldwide rights which includes the design. More Info
