Otto von Guericke used a water pump that he modified in order to pump the air out of two brass hemispheres that were joined together as a sphere. Then, in a famous demonstration, he used two teams of horses to try and pull the two hemispheres apart but they could not. He explained it was the pressure of the atmosphere that was holding the two halves together and that a vacuum could exist on earth.
What else can I help you with?
What did otto von guericke contribute to the particle theory?
Otto von Guericke contributed to the particle theory by conducting the famous Magdeburg hemispheres experiment which demonstrated the concept of a vacuum and the existence of air pressure. His work helped in understanding the nature of particles and their behavior in a vacuum.
What is the formula to calculate the thermal efficiency of an Otto cycle engine?
The formula to calculate the thermal efficiency of an Otto cycle engine is: Thermal Efficiency 1 - (1 / compression ratio)
Who was the German scientist who devised an internal combustion engine fueled by gasoline in 1886?
Otto (which started the term "Otto Motor" in Germany) In 1876 Nikolaus Otto built a four-stroke or "Otto cycle" internal combustion engine. Gottlieb Daimler & Wilhelm Maybach who had worked with Otto on his engine, parted company and in 1885 released their own much advanced version. In 1886 Karl Benz patented his "motorwagen" and is generally credited as being the father of the automobile.
What is the efficiency of the Otto cycle formula and how can it be optimized for maximum efficiency?
The efficiency of the Otto cycle is given by the formula: Efficiency 1 - (1 / compression ratio)(-1), where is the specific heat ratio. To optimize the efficiency of the Otto cycle for maximum efficiency, you can increase the compression ratio, improve combustion efficiency, reduce heat losses, and use higher octane fuel.
What is the relationship between thermal efficiency and the Otto cycle in internal combustion engines?
The thermal efficiency of an internal combustion engine using the Otto cycle is a measure of how effectively it converts heat energy from fuel into mechanical work. The Otto cycle, which consists of four processes (intake, compression, power, and exhaust), plays a key role in determining the engine's thermal efficiency. By optimizing the compression ratio and combustion process within the Otto cycle, engineers can improve the engine's thermal efficiency, resulting in better fuel economy and performance.
Who invented the pressure gauge?
Otto von Guericke invented the pressure gauge. Otto von Guericke was from Germany and was a scientist, inventor, and a politician.
Internal-combustion engine on diagram how induction on the otto cycle work?
The induction in Otto cycle is shown in the diagram at lower portion below atmospheric pressure(ATP) 0 to 1(from end of exhaust and starting of compression) the suction starts from ATP and then below ATP then to ATP due to the suction offered by piston from stored energy of fly wheel(ref.actual Otto cycle)
Compare Brayton and Otto cycle?
The heat addition and rejection processes in otto cycle are of constant volume, whereas in brayton cycle, they are of constant pressure.
How did the physiologist otto Frank of the Frank-starling curve die?
He couldn't withstand the pressure of a physiologist
Why does the heat is added at constant volume in Otto cycle and at constant pressure in Diesel cycle?
in otto cycle the burning of fuel is instantaneously therefore a very small voulme is required for burning of fule
What is the difference between otto cycle and diesel cycle?
the difference is the heat addition type In Otto Cycle the heat addition is Isochoric ((constant volume)) In Diesel Cycle the heat addition is Isobaric ((constant pressure))
What did otto van guericke invent?
Oh, dude, Otto von Guericke invented the vacuum pump in the 17th century. It's like this device that sucks out air from a space, creating a vacuum. So, yeah, he basically made it possible for us to understand the concept of a vacuum. Cool, right?
What is the birth name of Otto Malmberg?
Otto Malmberg's birth name is Otto Fredrik Malmberg.
What is otto in French?
Otto
What is the first name of chemistry nobelist otto?
The Chemistry Nobelist "Otto" is Otto Hahn. German who discovered nuclear fission. The prize was awarded him in 1944.
What nicknames does Otto Jespersen go by?
Otto Jespersen goes by the nickname "Otto" or "Otto Jr." in his comedy sketches and performances.
What has the author Otto Modersohn written?
Otto Modersohn has written: 'Otto Modersohn, Zeichnungen' -- subject(s): Exhibitions 'Otto Modersohn' 'Otto Modersohn 1865-1943'
