Interfaces are also provided for getting derivatives of fluid properties with respect to the input arguments. These interfaces are named the same as their non-derivative counterparts, but have no return value but 3 additional (output) arguments, corresponding to the property value and then the derivatives of each of the two input arguments. For example, $var element = document.getElementById("moose-equation-6a5fa896-89ed-4e10-99a7-c2c65e6e26f1");katex.render("\\rho(p,T)", element, {displayMode:false,throwOnError:false});$ has the interface rho_from_p_T(p, T, x, rho, drho_dp, drho_dT, drho_dx), where drho_dp, drho_dT, and drho_dx correspond to $var element = document.getElementById("moose-equation-bb47e8c6-5253-42bf-9db7-ae961195d8c5");katex.render("(\\partial\\rho/\\partial p)|_{T,\\mathbf{x}}", element, {displayMode:false,throwOnError:false});$ , $var element = document.getElementById("moose-equation-f2814236-a363-4d10-8dc3-e0306d798936");katex.render("(\\partial\\rho/\\partial T)|_{p,\\mathbf{x}}", element, {displayMode:false,throwOnError:false});$ , and $var element = document.getElementById("moose-equation-33a5a5d5-2006-4fa6-b2f2-62520aed0dde");katex.render("(\\partial\\rho/\\partial \\mathbf{x})|_{p,T}", element, {displayMode:false,throwOnError:false});$ respectively.

Additionally, the following interfaces are available:

getPrimaryFluidProperties(): The primary component of the mixture.
getSecondaryFluidProperties(i): The secondary component $var element = document.getElementById("moose-equation-d96d04e8-c317-4828-8443-77847d30608c");katex.render("i", element, {displayMode:false,throwOnError:false});$ of the mixture.
getNumberOfSecondaryVapors(): Returns $var element = document.getElementById("moose-equation-c1dace22-fecc-4e12-9845-8c5d881f6bd7");katex.render("n-1", element, {displayMode:false,throwOnError:false});$
numberOfComponents(): Returns $var element = document.getElementById("moose-equation-9681e5c4-dbd1-4e93-a37b-d4f8c24b0489");katex.render("n", element, {displayMode:false,throwOnError:false});$
primaryMassFraction(x_secondary): Computes $var element = document.getElementById("moose-equation-51a2fd9f-08b7-41bd-a0a9-19808fc8a42e");katex.render("x_1", element, {displayMode:false,throwOnError:false});$ from $var element = document.getElementById("moose-equation-ed3c5cf2-0e6e-4423-88ec-e1e1a620dfb6");katex.render("\\{x_2, \\ldots, x_n\\}", element, {displayMode:false,throwOnError:false});$
mixtureMolarMass(molar_fractions, molar_masses): Computes the mixture molar mass from the molar fractions and molar masses of all components
massFractionsFromMolarFractions(molar_fractions, molar_masses): Converts molar fractions to mass fractions
