Pressão Absoluta<\/h3>\n\n\n\n

Pressão absoluta<\/a> (psia) é a pressão<\/a> medida em relação ao vácuo absoluto, ou seja, inclui tanto a pressão<\/a> manométrica quanto a pressão atmosférica<\/a>. A fórmula básica para determinar a pressão absoluta<\/a> é: Pressa˜o Absoluta=Pressa˜o Manomeˊtrica+Pressa˜o Atmosfeˊrica\\text{Pressão Absoluta<\/a>} = \\text{Pressão<\/a> Manométrica} + \\text{Pressão Atmosférica<\/a>}<\/p>\n\n\n\n

Quando um instrumento de medição de pressão<\/a> está calibrado para indicar a pressão absoluta<\/a>, ele exibirá a pressão atmosférica<\/a> (aproximadamente 14,7 psi ao nível do mar) quando não houver nenhuma outra pressão<\/a> aplicada. Esse tipo de medição é utilizado, por exemplo, em manômetros<\/a> de pressão<\/a> do coletor<\/a> de motores a pistão, pois pode registrar valores inferiores à pressão atmosférica<\/a> (vácuo) ou superiores (se o motor for sobrealimentado).<\/p>\n","protected":false},"excerpt":{"rendered":"
