A tank with volume 10 m3contains hot water with temperature 190°F. From the table above the density of water at 190°F is 966.8 kg/m3. The totalmassof the water in the tank can be calculated 10 (m3) * 966.8 (kg/m3) =9668(kg) ...
Hence the reduced and presently used sample size (Nr = 49, Table 2) sufficiently represents the full population whilst omitting bias. Fig. 3 Effect of repeatedly sampling 40 random publications (Nsample = 40) on the a probability distribution of thermal conductivity ratio (knf/kbf), ...

Table 1 shows that the Schirmer values of \(D_{\textrm{w}0}\) are about 6 percent larger than the preferred values of Hellmann (or of Massman, which for practical purposes in building physics are the same). Hellmann estimates that the expanded (\(k=2\)) uncertainty in \(D_{\...
Groundwater in the Xiong’an New Area was neutral to weakly alkaline, with the pH between 6.7 and 9.5 (median, 7.7) and between 7.2 and 8.6 (median, 8.2) in shallow and deep aquifers, respectively (Table 1). Na+ was the dominant cation, and HCO3− was the major anion in both shal...
