Calculate Net Efficiency,given the Following: Resting VO₂ = 0

Multiple Choice

Calculate net efficiency,given the following: Resting VO₂ = 0.25 liters per minute
Exercise VO₂ = 1.50 liters per minute
Work rate = 100 watts (W) or 612 kilopond meters per minute
1 watt = 1 joule per second
1 kcal = 4186 joules
1 liter VO₂ = 5 kcal or 20,930 joules

A) approximately 19%
B) approximately 20%
C) approximately 23%
D) approximately 28%
