On the other hand, Jens and Lottes (1951) and Thom et al. (1965) presented empirical correlations that showed another dependence of wall superheat on pressure. Dependence of the dimensionless wall superheat = AroNB/A7Qj,jg on... 

Fluid-Specific Correlations. Since water is the most widely boiled fluid in forced convection (i.e., in power generation systems), it was natural that correlations specific to water were developed at an early stage. Perhaps the best known of such correlations is that of Jens and Lottes [252], which relates the wall superheat to the heat flux and pressure as follows... 

The U.C.L.A. data deviate +60 to -140% while the M.I.T. data range between +100% to -10% of the correlated values. Previously, Jens and Lottes " reported that...
