Notes:

  1. Table capacities are in kilowatts of refrigeration.
    triangle p = pressure drop per unit equivalent length of line, Pa/m
    triangle t = corresponding change in saturation temperature, K/m
  2. Line capacity for other saturation temperature Triangle Symbol t and equivalent lengths Le
    Line Capacity = Table Capacity [ Table Le X Actual Triangle Symbol t ] 0.55
