Теплообмінник виготовлений з товщиною стінки 6 мм із розрахунку його роботи під
внутрішнім тиском 0,6 МПа. Перед відправкою замовник змінив тиск на 0,8 МПа. Вам необхідно
встановити, чи можна експлуатувати апарат при цьому тиску або виготовити новий. Для цього
Вам необхідно розрахувати товщину стінки еліптичного відбортованого днища теплообмінника,
якщо внутрішній діаметр апарата 1200 мм, допустима напруження 134 МПа, коефіцієнт міцності
зварного шва 1,0. Обґрунтування.
