Liquid

We compute the liquid density at Patm and corrected temperature T:

Where the coefficients ρ0 and α are parameters which depend on the type of fuel.

Then we compute liquid density at P and T with the Bode’s equation given in figure Figure 7:

Equation 6: Density of liquid at P and T

The coefficients A, B1, B2, B3, B4 are determined by experimental measurements. They vary in function of the type of fuel.

The liquid bulk modulus can be computed from the Bode’s equation and Equation 2:
