        <p>Приведены новые $p, rho,T,x$-зависимости системы вода--1-пропанол, содержащей 0.1~мольной доли 1-пропанола в однофазной (жидкой, паровой) области, на линии кривой равновесия фаз жидкость--пар, в критической и сверхкритической областях в диапазоне по: температуре 403.15--673.15~К, плотности 31--712~кг/м$^{3}$ и давлению до 55~МПа, описанные термическим уравнением вириального вида со средней относительной погрешностью 1.2 %.  Проведен сравнительный расчет цикла Ренкина для паротурбинной установки на воде и на смеси вода--1-пропанол для различных составов $x$ в одинаковых термобарических условиях и установлено, что термический и эффективный КПД цикла Ренкина для смеси, содержащей $x$~=~0.1 мольные доли 1-пропанола, принимают максимальные значения.</p>

      <abstract xml:lang="en" abstract-type="summary">
        <p>The presented dependences p, r, T, x of the homogeneous binary water+1-propanol mixture (0.1 mole fraction of 1-propanol) were obtained in the single-phase (liquid, vapor) region, along the phase of the coexistence curve, in the critical and supercritical regions of the state parameters. These values were obtained in the regions of temperatures 403.15–673.15 K, densities 31–712 kg/m3 and pressures up to 55 MPa. The virial-type states described by the thermal equation with average percentage errors of the calculated pressure values relative to the experimental values are 1.2%. To evaluate the energy efficiency of the steam turbine unit, the water and water+1-propanol cycle under the same conditions have been calculated. It is found that the thermal and effective efficiencies for the water+1-propanol mixture (0.1 mol.fraction of 1-propanol) take the maximum values.</p>
