Problem 32PE

person in good physical condition can put out 100 W of useful power for several hours at a stretch, perhaps by pedaling a mechanism that drives an electric generator. Neglecting any problems of generator efficiency and practical considerations such as resting time: (a) How many people would it take to run a 4.00-kW electric clothes dryer? (b) How many people would it take to replace a large electric power plant that generates 800 MW?

Step-by-Step Solution:

Step-by-step solution Step 1 of 3 The formula to find the power is, Here is the power, is the work done and is the time period. A person in good physical condition can put out 100 W of useful power for several hours at a stretch. Step 2 of 3 (a) Let be the number of people that would take to run a 4.00 kW electric clothes dryer. Therefore, Therefore, the number of person required is .
