6 However, the inlet air is 25 F higher than standard day (75 F vs. 50 F), so we must correct for this by multiplying HPs by the square root of the temperature ratio (adjusting for absolute, or Rankine, temperature).Thus, 139x [(460+50)/(460+75)]^ = HP 9 of 13 Corporate Offices . 621 South Royal Lane .
