Quem é Evangelista Torricelli? , a invenção do barômetro

Evangelista Torricelli nasceu em 15 de outubro de 1608, na cidade italiana de Faenza, morreu em 5 de outubro de 1647 em Florença. Ele é o famoso cientista italiano de física e matemática conhecido por suas experiências sobre a pressão do ar aberto.

 

Chamou a atenção para sua curiosidade da infância sobre a matemática. Em 1627 ele foi para Roma e trabalhou com Benedetto Castelli, o fundador da ciência hidráulica e da demanda de Galilei. Ele começou a correspondência com Galilei em 1641. No mesmo ano, na recomendação de Castelli, Galileu convidou Torricelli para a Toscana. Algumas semanas depois da reunião com Galileu, quando Galilei morreu, ele transferiu Torricelli, o grande Duque da Toscana, para seu escritório. Em 1644 ele publicou um livro sobre geometria e mecânica. Neste livro, que preenche uma lacuna importante no campo da matemática, o primeiro trabalho da mecânica de Galileu, os centros de gravidade comum de corpos interligados, mover para baixo, enquanto o princípio de movimentos repentinos pode ser que ele estava se conectando.

 

Em vez de água, Torricelli teve a sabedoria de colocar o pintinho (mina líquida), que era mais pesado do que treze vezes e meia, por isso a altura da coluna foi encurtado igualmente. Assim Torricelli executou o primeiro barômetro; Uma extremidade está obstruída e um tubo de vidro enchido com o mercúrio. Este tubo é virado de cabeça para baixo, ea extremidade aberta é mergulhado em uma banheira cheia de mercúrio novamente. Parte do mercúrio no tubo flui para dentro da banheira e a coluna de mercúrio desce até 760 milímetros no tubo. Então o peso do mercúrio é equivalente à pressão atmosférica. Como resultado das experiências com tubos cheios de mercúrio, a pressão no nível do mar foi de 1033 gr/cm ². Em geometria e mecânica, ninguém se importava com suas idéias primeiro. Torricelli também tentou desenvolver seu mentor, o telescópio de Galileu e seu próprio microscópio.

 

1643 Torricelli já inventou o dispositivo chamado o barômetro Mercury para medir a pressão do ar.

 

Ao mesmo tempo, Blaise Pascal pensou em usar o barômetro para medir a elevação. Uma vez que o peso da atmosfera determina a altura do mercúrio dentro do tubo, esta altura será reduzida em cima de uma montanha; No topo da montanha, a altura da camada de ar é menor do que o nível do mar e o peso será menor. Consequentemente, a altura da coluna de mercúrio indica em que altitude estamos: esta é a essência do altímetro (medidor de elevação).

 

Mais tarde, as mudanças na atmosfera, reduzindo o peso da atmosfera e replicando a altura da coluna de mercúrio foi compreendido. Assim, a previsão de mudança de ar foi aprendida olhando para os marcadores de barômetro; Conformemente, ao nível do mar, mercúrio a uma altura de 760 milímetros é um sinal de "tempo bonito". A pressão atmosférica também pode ser medido por barómetros de minas, que são latas de ar drenado.

 

Como é que funciona?

 

O aumento da pressão do ar move a coluna de mercúrio e fornece elevação para o braço esquerdo. Enquanto isso, o nível de mercúrio no braço direito diminui. O peso que é muito pouca luz flutua sobre Mercúrio e sobe com ele. A corda e o carretel, dependendo do peso e do contrapeso, trabalham como uma plataforma da polia e podem mover-se junto. Enquanto a pressão de ar aumenta, o contrapeso deteriora-se e o mercúrio aumenta, mais baixo a pressão de ar, maior o contrapeso e o mais baixo o nível do mercúrio. Isto faz uma medição clara e precisa.

 

Barómetro da barra

 

O princípio de funcionamento do barómetro da barra é muito simples. A pressão de ar aplicada ao reservatório direito é a maior pressão sobre o nível do mar e o nível de fluido no braço esquerdo aumenta. A lacuna no braço esquerdo deve ser um vácuo. Se houver um gás, a pressão sobe e começa a empurrar. Isso faz com que a medida apareça abaixo do valor real.


 

Barômetro aneróide

 

A cápsula de vácuo carrega um movimento ' B ' com ligeiro progresso com a mudança de pressão de ar ' a '. Uma pequena alavanca, ' C', fortalece este movimento e transmite-o para o ' e ' Reel através da pequena cadeia ' d '. O ' F ' posicionado na bobina mostra o resultado mais preciso graças à barra de indicadores e ao estabilizador ' g '.
