 The temperature should be measured after a run of sufficient duration to reach practical constancy. This is usually from 6 to 18 hours, according to the size and construction of the apparatus. It is permissible, however, to shorten the time of the test...  Electric Lighting ... - Сторінка 367автори: Francis Bacon Crocker - 1904Повний перегляд - Докладніше про цю книгу
