Solution # 10 (Pete-2032)
For ideal solution case in 12-1, following derivation was made.
Let, the components be 1 & 2 for the binary mixture.
By applying Raoults law, x1*Pv1+x2*Pv2=P
=> x1 =(P-Pv2)/(Pv1-Pv2
As fluids are produced from reservoirs, the conditions of their existence, namely pressure,
temperature and composition change.
Major fluids: gas, oil, water
Also produce sand
