Problem 32PE
A 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?

Problem 32PE
A 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?
ANSWER:
Solution 32PE
Step 1 az
We have to calculate the number of persons required to run clothes dryer and the number of persons required to replace a large power plant which outputs a power of .
Given data:
The power output of a person,
Power requirement of clothes dryer,
Power output of a large electric generator,
