💢 سیالات محاسباتی و شبیه سازی عملکرد پمپ سانتریفیوژ
⚙️ این نوع پمپ‌ها بر اساس نیروی گریز از مرکز عمل میکند، سیال به مرکز پمپ و پای پره‌های پروانه وارد می‌شود. در اثر کاهش فشار، پروانه توسط الکتروموتور با سرعت بالا دوران میکند و سیال حرکت میکند. لذا انرژی جنبشی آن افزایش می‌یابد و در اثر نیروی گریز از مرکز به طرف خارج پرتاب می‌شود و پوسته پمپ را پر از سیال میکند. در نهایت انرژی جنبشی مایع به دلیل طراحی خاص مجرای خروجی پمپ به انرژی پتانسیل فشار تبدیل می‌گردد.

Investors took profits on Friday while they could ahead of the weekend, explained Tom Essaye, founder of Sevens Report Research. Saturday and Sunday could easily bring unfortunate news on the war front—and traders would rather be able to sell any recent winnings at Friday’s earlier prices than wait for a potentially lower price at Monday’s open. Messages are not fully encrypted by default. That means the company could, in theory, access the content of the messages, or be forced to hand over the data at the request of a government. Two days after Russia invaded Ukraine, an account on the Telegram messaging platform posing as President Volodymyr Zelenskiy urged his armed forces to surrender. Since its launch in 2013, Telegram has grown from a simple messaging app to a broadcast network. Its user base isn’t as vast as WhatsApp’s, and its broadcast platform is a fraction the size of Twitter, but it’s nonetheless showing its use. While Telegram has been embroiled in controversy for much of its life, it has become a vital source of communication during the invasion of Ukraine. But, if all of this is new to you, let us explain, dear friends, what on Earth a Telegram is meant to be, and why you should, or should not, need to care. But Telegram says people want to keep their chat history when they get a new phone, and they like having a data backup that will sync their chats across multiple devices. And that is why they let people choose whether they want their messages to be encrypted or not. When not turned on, though, chats are stored on Telegram's services, which are scattered throughout the world. But it has "disclosed 0 bytes of user data to third parties, including governments," Telegram states on its website.
