Chapter 3, Problem 3.8Q
Interpretation Introduction
Interpretation:
The correct word for the given statement should be determined.
Concept Introduction:
The effect of temperature on plastics is complex in nature. When heated, plastics become flexible before finally melting. However, upon cooling it can regain its rigidity and may become hard yet brittle. This is due to the present of amorphous and crystalline regions. Amorphous regions represent the phase when the polymeric chains are not arranged in an organized manner. Similarly, crystalline regions represent the phase when polymeric chains are well organized. A crystalline plastic may transit from strictly crystalline to amorphous state under constant heating.

A forward feed double-effect vertical evaporator, with equal heating areas in each effect, is fed with 5 kg/s of a liquor of specific heat capacity of 4.18 kJ/kg K. and with no boiling point rise, so that 50 per cent of the feed liquor is evaporated. The overall heat transfer coefficient in the second effect is 75 per cent of that in the first effect. Steam is fed at 395 K and the boiling point in the second effect is 373 K. The feed is heated by an external heater to the boiling point in the first effect. It is decided to bleed off 0.25 kg/s of vapour from the vapour line to the second effect for use in another process. If the feed is still heated to the boiling point of the first effect by external means, what will be the change in steam consumption of the evaporator unit?
