Smart Flow Calculator

The following takes a typical intelligent traffic calculator as an example to illustrate the implementation method of automatic table lookup. 5 in Smart Flow Calculator: ? There are 3 steam density tables written in 110^, the No. 1 table is superheated steam density table, and the other two are saturated steam density tables [see Appendix 0, all of which are calculated by the formula of International Steam Density Table 1967 11^. Among them, the superheated steam density table has two independent variables of steam temperature and steam pressure. Table No. 2 is the steam pressure as the independent variable. Table No. 3 is steam temperature as an independent variable. In this way, the measured steam temperature or the measured steam pressure can obtain the steam density by looking up the table. Whether to check the '^/(^ table or ^^/(纟) table is selected by the user when filling in the configuration menu. The priority of table lookup. The density of superheated steam changes with steam temperature and pressure The relationship is a curved surface in three-dimensional space, and there are two independent variables, so there is a priority problem when checking the density table. If you check from the pressure first, it is called the pressure priority; if you check from the temperature first, it is called Temperature takes precedence.
