WOWW Kan man få en lille forklaring på de forkortelser.?

jo jo

mc (g) = grain krugt
fill (%) = % fyldning af hylester m projektil i
vel (m/s) = hastighed m/s
Pmax (MPa) = tryk i Mpa / megapascal
Z (%) = % forbrændt krudt
t (ms) = den tid kuglen er i piben i milisekunder
Pmuz (MPa) = mundingstryk i Mpa

Super. Mange tak for din tid og svar.
