S\u00fcrt\u00fcnmenin ihmal edildi\u011fi, s\u0131k\u0131\u015ft\u0131r\u0131lamaz ve daimi bir ak\u0131\u015f hatt\u0131 boyunca toplam mekanik enerji sabit kal\u0131r. Bu durum, di\u011fer ko\u015fullar de\u011fi\u015fmedi\u011finde ak\u0131\u015fkan h\u0131z\u0131n\u0131n artt\u0131\u011f\u0131 b\u00f6lgelerde statik bas\u0131nc\u0131n azalmas\u0131 anlam\u0131na gelir.<\/p>\n

R\u00fczg\u00e2r \u015femsiyeye \u00e7arpt\u0131\u011f\u0131nda hava ak\u0131\u015f\u0131 \u00fcst ve alt y\u00fczeylerden farkl\u0131 bi\u00e7imlerde ilerler. \u015eemsiyenin \u00fcst k\u0131sm\u0131nda hava daha h\u0131zl\u0131 hareket ederken alt k\u0131sm\u0131nda daha yava\u015f hareket eder. Bernoulli ilkesine g\u00f6re daha h\u0131zl\u0131 hareket eden havan\u0131n bulundu\u011fu b\u00f6lgede statik bas\u0131n\u00e7 azal\u0131r. B\u00f6ylece \u00fcst ve alt y\u00fczeyler aras\u0131nda bir bas\u0131n\u00e7 fark\u0131 olu\u015fur.<\/p>\n

Bu bas\u0131n\u00e7 fark\u0131 \u015femsiyeye yukar\u0131 y\u00f6nl\u00fc bir kuvvet uygular. Ortaya \u00e7\u0131kan kald\u0131rma kuvveti, r\u00fczg\u00e2r h\u0131z\u0131 artt\u0131k\u00e7a do\u011frusal de\u011fil, h\u0131z\u0131n karesiyle orant\u0131l\u0131 olarak b\u00fcy\u00fcr. \u00d6rne\u011fin r\u00fczg\u00e2r h\u0131z\u0131n\u0131n iki kat\u0131na \u00e7\u0131kmas\u0131, bas\u0131n\u00e7 fark\u0131n\u0131 yakla\u015f\u0131k d\u00f6rt kat art\u0131rabilir.

Metro istasyonlar\u0131ndaki g\u00fcvenlik \u015feridi: Trenlerin \u00e7evresindeki hava neden tehlikelidir?<\/strong><\/h2>\n

Bernoulli ilkesinin etkileri yaln\u0131zca g\u00fcnl\u00fck ya\u015famda de\u011fil, m\u00fchendislik uygulamalar\u0131nda da kar\u015f\u0131m\u0131za \u00e7\u0131kar. Metro istasyonlar\u0131ndaki peron kenarlar\u0131nda bulunan sar\u0131 g\u00fcvenlik \u00e7izgileri bunun dikkat \u00e7ekici \u00f6rneklerinden biridir.<\/p>\n

H\u0131zla perona yakla\u015fan veya perondan ge\u00e7en bir tren, \u00e7evresindeki havay\u0131 s\u00fcr\u00fckleyerek g\u00fc\u00e7l\u00fc hava ak\u0131mlar\u0131 ve bas\u0131n\u00e7 de\u011fi\u015fimleri olu\u015fturur. Tren ile peron aras\u0131ndaki dar b\u00f6lgede hava ak\u0131\u015f\u0131 h\u0131zlan\u0131r. Bernoulli ilkesine g\u00f6re hareket eden havan\u0131n h\u0131z\u0131 artt\u0131\u011f\u0131nda statik bas\u0131n\u00e7 azal\u0131r. Yolcu trene \u00e7ok yak\u0131n durursa arkas\u0131ndaki daha y\u00fcksek bas\u0131n\u00e7 ile \u00f6n\u00fcndeki daha d\u00fc\u015f\u00fck bas\u0131n\u00e7 aras\u0131ndaki fark tehlikeli kuvvetlerin olu\u015fmas\u0131na katk\u0131da bulunabilir.<\/p>\n

Trenin olu\u015fturdu\u011fu tehlike yaln\u0131zca bu bas\u0131n\u00e7 fark\u0131ndan kaynaklanmaz. H\u0131zl\u0131 hava ak\u0131mlar\u0131, t\u00fcrb\u00fclans ve tren g\u00f6vdesinin olu\u015fturdu\u011fu di\u011fer aerodinamik etkiler de ki\u015finin dengesini bozabilecek kuvvetler ortaya \u00e7\u0131karabilir. Bu nedenle yolcular\u0131n g\u00fcvenlik \u00e7izgisinin gerisinde durmas\u0131 \u00f6nemlidir. Tren yakla\u015ft\u0131k\u00e7a hava hareketleri daha karma\u015f\u0131k h\u00e2le gelir; ani hava ak\u0131mlar\u0131 ve d\u00fczensiz girdaplar ki\u015finin dengesini etkileyebilir. Bernoulli ilkesi bu olayda hava h\u0131z\u0131 ile bas\u0131n\u00e7 aras\u0131ndaki ili\u015fkiyi a\u00e7\u0131klayan temel fizik prensiplerinden biridir ancak ger\u00e7ek durum, ak\u0131\u015fkanlar mekani\u011fine ait bir\u00e7ok farkl\u0131 etkinin birlikte ortaya \u00e7\u0131kmas\u0131yla olu\u015fur.<\/p>\n
