Lecture 10: From Experimentation to Utility of Industrial Revolution Flashcards
What is the purpose of the steam engine?
It was to serve the navy and replace the highly demanded resource, wood.
What is the aftermath of restricting wood?
It introduce coal as the new form of fuel
What is the purpose of steam engines in mining shafts?
Used as power pumps to mine coal
Who is Thomas Savery (1650–1715)?
He was consider the “fathers” of steam engine that invented, “Miner’s friend” (1698)
Why did Dr. Lech state that Thomas Savery is not the inventor of the steam engine?
He got the first patent, however, he did not understand the scientific principle behind the device. (He copied it from someone)
Who did Thomas Savery copy from?
He copied from Edward, Marquise of Worcester (1663)
What is the flaw of the Steam engine?
The steam engine was a vacuum pump that cannot operate under 12 m.
Who is Denis Papin (1647 - C. 1712)?
A forgotten inventor that invented:
- piston cylinder steam engine (1690)
- steamboat (1681 - 1708)
Why is Denis Papin forgotten?
Similar to John Harrison, he was a foreigner from France.
Who is attributed by the piston cylinder steam engine?
Thomas Newcomen and James Watt
What is the piston cylindrical steam engine based on?
It was base on Archimedean fire engine or vacuum pump
Why did Denis Papin fail?
- Inadequate technology (internal)
- Social issue (external)
Show the social connections of Denis Papin.
- Before 1691: Denis Papin -> Robert Boyle (Assistant) -> Robert Hooke (Curator of experiments) / Royal Society of London
- After 1691: Denis Papin -> Robert Boyle -> Isaac Newton/ Royal Society of London
- After 1703: Denis Papin -> Isaac Newton (head of the Royal Society of London)
- 1708: Denis Papin (sending proposal) -> Thomas Savery’s interferes / The Royal Society -> Isaac Newton (Head of the Royal Society)
What did Thomas Savery’s letter state in regard to Denis Papin?
- He was a French foreigner
- The valve of the steam engine must be set manually (although, the valve can move automatically)
- Thomas Savery is the true inventor of the steam engine
Who said, “simplest and cheapest experiments first” and what does it mean?
Isaac Newton made that statement to Denis Papin during his proposal and telling Papin to restart to the very beginning of his experiment
What was Denis Papin rewarded for after his death?
He was awarded for being the inventor of the pressure cooker
Who is Thomas Newcomen (1663–1729)?
A self-proclaimed inventor of the pistion and cylinder steam engine
List the improvements of the modified invention?
- Original steam engine can only operate at 12 rpm
- Steam and partial vacuum:
Steam is admitted into the cylinder -> cold water injected as the hot steam enters the cylinder creating condensation -> partial vacuum sucked the piston into the cylinder -> motion
What model of Thomas Newcomen located?
Glasgow University
Who was responsible for maintenance on the model?
James Watt
Who is James Watt?
A trader and scientific instrument maker that use to be a shopkeeper
What makes James Watt unique?
He modified Thomas Newcomen’s invention by accommodating the loss of energy in the model
How does James Watt accommodate the issue?
Introduce an external steam condenser, replaced the atmospheric pressure with low pressure steam. Therefore, the model is entirely powered by vacuum
Who is Matthew Boulton (1728–1809)?
A famous industrialist that used to supply iron ornaments to James Watt
What did Matthew Boulton see James Watt’s invention as?
See James Watt’s invention as a profit, thus, obtain the patent of the steam engine through the British parliament
How did Matthew Boulton meet James Watt?
They met at the Lunar society
What problems did James Watt and Matthew Boulton faced?
They couldn’t get the steam engines to work. This was due to the precision of the metallurgy. Ultimately, this led to the cylinder not matching the piston
What is Dr. Lech suggestion to fixing this problem?
Rather than casting them, they need a way to bore precisely the cylinders of chunk of metal
What is a good example to fixing this problem?
The cannon has the same problem, as not enough precision was unable to prevent cracks during explosion. However, John Wilkinson would introduce the bore cannons
What is John Wilkinson’s obsession?
He was obsessed with standardization and precision
Although there is one more technology by James Pickard, why didn’t James Watt pay pickard’s patent?
He wanted to avoid paring the patent fee by changing the initial design to have his own patent
