Thiết bị tạo huyền phù hình trụ đường kính D = 1,2m, chiều cao Ht = 1,1m, chứa đầy ¾ huyền phù. Biết ⍴h = 1000kg/m3, = 1cP. Dùng cánh khuấy chong chóng dk = 0,4m với số vòng quay n = 400v/phút, hệ số Kd = 1,4; hiệu suất ɳ = 0,8, bình không tấm ngăn. Tính công suất động cơ?

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?
