A Breakneck Introduction to the Industrial Revolution Most stuff comes out of mines.. But they tend to flood . We need to invent the handpump We ve potentially solved the problem of what to use Arts Graduates for . https://www.youtube.com/watch?v=UmZYQ5I0CDU
Except it turns out that arts graduates need to eat and are therefore expensive so we invent the steam engine P V The boiler generates super heated air . That we release into the space below the piston
Except it turns out that arts graduates need to eat and are therefore expensive so we invent the steam engine P V The hot air expands (basically at constant T so P ~ 1/V) and pushes the piston up
Except it turns out that arts graduates need to eat and are therefore expensive so we invent the steam engine P V We inject cold water into the piston, cooling the air and dropping the pressure
Except it turns out that arts graduates need to eat and are therefore expensive so we invent the steam engine P V Now the piston falls under its own weight (gravity does the work)
Except it turns out that arts graduates need to eat and are therefore expensive so we invent the steam engine P work V We ve done work by moving the top beam which is attached to the pump We have done one cycle and are ready to go again
Except it turns out that arts graduates need to eat and are therefore expensive so we invent the steam engine P work V Clever rods automatically open the valve to let steam in and start the next cycle . The arts graduate problem remains
Take away messages People made engines that do work using energy flowing from a hot source to a cold sink Engineers can make some nifty gadgets with sticks they used a variety of designs and materials and they wondered what the best material and design was Carnot idealized the engines and showed these questions are not the deep point No Arts Graduate were made to work in the making of this slide show
