Problem 50PE

What is the efficiency of a subject on a treadmill who puts out work at the rate of 100 W while consuming oxygen at the rate of 2.00 L/min? (Hint: See Table 7.5.)

Step-by-Step Solution:

Solution 50PE

We are required to calculate the efficiency of a person using the treadmill under the given condition. Efficiency is the ratio of the input to the output work.

Mathematically,

Step 1 of 2</p>

The rate at which the person consumes oxygen is 2.00 L/min. Table 7.5 says that this rate corresponds to cycling (21 km/h), having an energy consumption rate of 700 W.

Step 2 of 2
