Redlich–Kwong modelisation[edit]

Formula seems to be missing something. Rearrangement of the formula on Redlich–Kwong equation of state gives
$RT=P(V_{m}-b)+{\frac {a}{V_{m}(V_{m}+b)T^{\frac {1}{2}}}}(V_{m}-b)$ .

Ni model section probably written by the authors themselves[edit]

Evidence:

The section is written by an IP address 1.65.205.26 and 1.65.205.125, which traces to Hong Kong -- perhaps a VPN, since the authors are located within China.

The abstract states that > A general and simple state equation for all gases is proposed based on the theory that the elastic collision between the boundary and gas molecules contributes the pressure, whilst the completely inelastic collision contributes the exchange of heat between the gas and the surrounding via boundary. In addition, at the high density and temperature, the high frequency of collision abates the distance of molecular motion, thus the effect of molecular mass is significant. Therefore, the gravity is introduced into the state equation.

The parentheses used are actually Chinese-style parentheses.

The paper has had no citations so far. Yet somehow it got into Wikipedia just 5 months later. pony in a strange land (talk) 23:53, 5 July 2023 (UTC)[reply]
