Show :LNox Reduction by Low Pressure Steam Addition" specific heat and slope of the specific volume, rows 11 & 13 are for 300°F minus saturated value. The polynomial coefficients are functions of PSIA, shown on rows 3 1 to 40 columns I to L Rows 15 through 22 are the ratio of the calculated values to the steam table values, useful in spotting false entries. The slopes (l>P / l)p) T of linear trend lines were based on steam table data at 250, 300 and 350°F., rows 24-26. 3 4 5 6 7 8 9 1 0 1 , 1 2 1 3 , 4 1 5 1 6 1 7 1 8 1 9 2 0 2 1 2 2 2 3 2 4 2 5 2 6 2 7 2 8 2 9 3 0 3 1 3 2 3 3 3 4 3 5 3 6 3 7 3 8 3 9 4 0 H PSIA Sat.
