Doymuş suyun bazı termofiziksel özellikleri için basit korelasyonlar

Bu çalışmada, bilgisayar destekli hesaplama yazılımlarında kullanılmak üzere, 0.01 370°C sıcaklık aralığında doymuş suyun bazı termofiziksel özellikleri için basit korelasyonlar geliştirilmiştir. Çalışılan termofiziksel özellikler yoğunluk, sabit basınçta özgül ısı, ısı iletim katsayısı ve dinamik viskozitedir. Eğri uydurma işleminde en küçük kareler yöntemi kullanılmıştır. Her bir termofiziksel özellik için seçilen korelasyonlar, geçerli olduğu sıcaklık aralığı, doğrusal korelasyon katsayısı, maksimum mutlak hata ve maksimum yüzde hata değerleriyle birlikte verilmiştir.

Simple correlations for some thermophysical properties of saturated water

In this study, simple correlations were developed for some thermophysical properties of saturated water at 0.01 370 °C temperature for use in computer-aided calculation software. Studied thermophysical properties are density, specific heat at constant pressure, heat transfer coefficient and dynamic viscosity. In order to fit the curves data, the least squares method has been applied. Correlations chosen for each thermophysical property have been given together with the valid temperature range, linear correlation coefficient, maximum absolute error, and maximum percent error.
