Quantity of adding refrigerant
= (Length of ø9.52 liquid pipe x 80g/m) + (Length of ø6.35 liquid pipe x 50g/m)
= (40m x 80g/m) + (20m x 50g/m)
= 4200g

Quantity of adding refrigerant =
Total length of piping x quantity of adding refrigerant per metre - standard quantity(1100g)

Quantity of adding refrigerant
= (Length of ø12.70 liquid pipe x 140g/m) + (Length of ø9.52 liquid pipe x 80g/m) + (Length of ø6.35 liquid pipe x 50g/m) - 1100g
= (20m x 140g/m) + (25m x 80g/m) + (25m x 50g/m) - 1100g
= 4950g
