As temperature decreases a ductile material can become brittle - ductile-to-brittle transition
1 answer:
Answer:
Yes ,at low temperature ductile material behaves like brittle.
Explanation:
Yes,as temperature decreases a ductile material can become brittle.
In metals ductile to brittle transition temperature is around 0.1 to 0.2 Tm(melting point temperature) and in ceramics ductile to brittle transition temperature is around 0.5 to 0.7 Tm(melting point temperature) .
We can easily see that from graph between fracture toughness and temperature.In the graph when temperature is low then the ductile material is behaving like brittle material.But when temperature is above a particular value then material behaves like ductile.

Answer:
51.4 Ohms
Explanation:
By applying voltage division rule
where v is voltage, subscripts i and f represnt initial and final, R is resistance, m is internal and l is external.Substituting 7V for final voltage, 10V for initial voltage and the external resistance as 120 Ohms then
Answer:
5.118 m^3/hr
Explanation:
Given data:
viscosity of cell broth = 5cP
cake resistance = 1*1011 cm/g
dry basis per volume of filtrate = 20 g/liter
Diameter = 8m , Length = 12m
vacuum pressure = 80 kpa
cake formation time = 20 s
cycle time = 60 s
<u>Determine the filtration rate in volumes/hr expected fir the rotary vacuum filter</u>
attached below is a detailed solution of the question
Hence The filtration rate in volumes/hr expected for the rotary vacuum filter
V' = ( ) * 1706.0670
= 5118.201 liters ≈ 5.118 m^3/hr
