• For intermediate H values, the value that corresponds to the lower H value from the table considered.
Example:
For H=1.25 m, the value that corresponds to H=1.20 m is considered.
• For intermediate mexcess values, the value that corresponds to the higher mexcess value from the table is
considered.
Example:
If mexcess =1.45 kg, the value that corresponds to m
c
=1.6 kg is considered.
