Deck 26: Appendix

Question 1

Calculate V BTPS and V STPD given:
V ATPS = 45.3 liters
Laboratory temperature = 19°C
Ambient barometric temperature = 746 mm Hg
Body temperature = 37°C

Answer 1

V BTPS = 50.19 liters
V STPD = 40.65 liters

Question 2

Calculate VO₂ and VCO₂ given:
V E (ATPS) = 100 liters · min 1
F E O₂ =.1768
F ECO₂ =.0351
Assume F I O₂ =.2093 and F ICO₂ =.0003
Ambient temperature = 21°C
Barometric pressure = 749 mm Hg

Answer 2

VO₂ = 2.73 · min 1
VO₂ = 3.54 · min 1

Question 3

Calculate the respiratory exchange ratio (R) from VO₂ and VCO₂ values computed in question 1.

Answer 3

R = 1.15
