The user's manufacturer's data indicate that for the turbine he ismodeling, it would be more accurate to change the first coefficient to0.022105. As the third coefficient is zero, the curve may be represented inthe form z = a + bx. The input might look like:INPUT PLANTG-EXH-H = CURVE-FITTYPE = LINEARCOEFFICIENTS = (0.022105, 0.000029)EQUIPMENT-QUADGTURB-EXH-FT = G-EXH-HENDIV.185 (Revised 5/81)
