Answer 1

Zadanie 1

Dane:

mr1=500g

mr2=500g+50g=550g

Cp1=20%

Szukane:

ms1=?

ms2=?

Cp2=?

ms1=Cp1*mr1/100%

ms2=ms1+50g

Cp2=ms2*100%/mr2

Obliczenia:

ms1=20%*500g/100%

ms1=100 g

ms2=100g+50g

ms2=150 g

Cp2=150g*100%/550g

Cp2=27,27%

Zadanie 2

Dane:

mr1=500g

Cp1=12%

Cp2=30%

Szukane:

ms=?

mr2=?

mH2O odparowanej=?

ms=Cp1*mr1/100%

mr2=ms*100%/Cp2

mH2O odparowanej=mr1-mr2

Obliczenia:

ms=12%*500g/100%

ms=60g

mr2=60g*100%/30%

mr2=200g

mH2O odparowanej=500g-200g

mH2O odparowanej=300 g
