Slide Notes

Each individual made improvements on the previous design.

Watt's use of a separate condenser, too cool the water, heralded the start of the industrial revolution.

Yes, that's where watt came from
1 watt = 1/746 of a horsepower

work is done by

the expansion of water as it's heated

in common

water
pump
energy
expander
condenser

water .... fluid to transfer work
pump - to pressurize the water
energy - to change the water's state
expander - to transfer the work from chemical to mechanical
condenser - to reuse the water
tank - storage

where would the engine work harder

Toronto or Calgary?

How does air pressure effect engines?

Does it take more or less fuel to boil water as you have less air pressure?

Newton's 1st Law

Things like to keep on doing what they're doing

Objects at equilibrium won't accelerate.

Your boat will sit there until the steam does something.

2nd f = ma

force equals mass x acceleration

If mass stays the same, the more force, the more acceleration.

If mass changes, but the forces doesn't, the acceleration will change.

1 newton = 1 kg m/s2

If

mass = 2kg, force = 10N, A =?

Using the equation...

F = MA

10 = 2A

or A = 10/2

A = 5m/s2

This means, the thing accelerates by 5m/s every second.

If I doubled the force, what would happen?

If I doubled the mass?
