You want to describe the real behavior of acetylene, which is to be loaded into a tank truck with 6 5 m ^ 3 .

You want to describe the real behavior of acetylene, which is to be loaded into a tank truck with 65 m^3. The virial equation in Berlin form is available to you:
z=p*v/(Ra*T)=1+B'(T)*p //// B'(T)=B(T)/(Ra*T) and B(T)=lim \rho goes 0(Z/\rho )T
In addition, the vapor pressure of acetylene in the temperature range under consideration can be described using the Antoine equation:
log10(x)= A - B /(T + C) ; A=4,66141 B=909,079 C=7.947
Consider the loading process approximately as a reversible isothermal compression with an initial pressure p=1 bar. The specific gas constant of acetylene is R =320 J/(kg K)
a) Calculate the vapor pressure of acetylene at T1=30\deg C.
b) Calculate B(T1). To do this, use the following van der Waals (vdW) parameters of acetylene avdW=668Pa m^6kg^2 and bvdW=2.0110^3m^3kg^1.
Hint: Make an expression for zvdW. Then use the given definition of B(T). p =( Ra*T /(v- bvdW))- avdw / v^2
C ) Calculate the maximum mass of gaseous acetylene that can be loaded into the tanker.
D) Calculate the specific entropy change of acetylene after loading using the virial equation. Assume the total differential of the entropy and use the function B(T) calculated in b).
s2s1=... J/(kgK)
E) Calculate the specific enthalpy change of acetylene after loading using the virial equation. Start from the total differential of the enthalpy and use the function B(T) calculated in b).
h2h1=... kJ/kg
F) f) Calculate the specific amount of heat transferred after loading using the virial equation.
q12=... kJ/kg
