Textbook Question
Chapter 4, Problem 4.27P
A paint mixture containing 25.0% of a pigment and the balance binders (which help the pigment stick to the surface) and solvents (which ensure that the paint stays in liquid form) sells for $18.00/kg, and a mixture containing 12.0% sells for SlO.OO/kg.
- If a paint retailer produces a blend containing 17.0% pigment, for how much (S/kg) should it be sold to yield a 10% profit?
- Paint manufacturers have begun to market “low VOC” paint as a more environmentally friendly product. What are VOCs? List some w'ays in w hich paint products can be altered to lower the VOC content.

- 14.9. 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? For the purpose of calculation, the latent heat of the vapours and of the steam may both be taken as 2230 kJ/kgarrow_forwardExample(3): It is desired to design a double effect evaporator for concentrating a certain caustic soda solution from 12.5wt% to 40wt%.
