How can i improve fastness properties of nylon dyeing?
Start by soaking your nylon in a mixture of 50 percent water and 50 percent distilled vinegar for at least a half-hour. Then use a pure acid dye according to the instructions that come with it.
There are two kinds of dyes: acid dyes and fiber reactive dyes. Fiber reactive dyes won't stick to nylon. Acid dyes will. Now, when you buy a box of Rit dye you are getting half a box of fiber reactive dye and half a box of acid dye - this helps them ensure that the thing you are dyeing will turn color. Problem is, the half a box of reactive dye doesn't do anything to the nylon, so half your money is going down the drain unused. There are a lot of places online that have the right dyes for you.
What does permeability depend on?
Permeability depends on membrane solubility and the presence of specific integral transport proteins.
Other factors such as pressure, concentration, and temperature of the molecules or solutes on either side, as well as the size of the molecules can also affect permeability.
How many students are studying in chemical engineering in govt chemical college thrissur?
I'm sorry, but I don't have access to real-time data, including the current number of students studying chemical engineering at Government Chemical College, Thrissur. For the most accurate and up-to-date information, I recommend checking the college's official website or contacting their administration directly.
What is sealing of pump shaft?
Sealing of a pump shaft refers to the mechanisms used to prevent the leakage of fluids along the shaft that connects the pump's motor to its impeller. Common sealing types include mechanical seals, packing seals, and lip seals, which ensure the containment of the pumped fluid while allowing the shaft to rotate. Proper sealing is crucial for maintaining efficiency, preventing environmental contamination, and prolonging the lifespan of the pump. Effective sealing also reduces maintenance costs and downtime associated with leaks.
What the advantages of printed circuit Heat exchanger?
Printed circuit heat exchangers (PCHEs) offer several advantages, including high thermal efficiency due to their large surface area and compact design, which allows for effective heat transfer in a smaller footprint. Their robust construction and resistance to pressure and temperature variations make them suitable for demanding applications. Additionally, PCHEs can be customized for specific needs, enhancing their versatility in various industries. Their low maintenance requirements further contribute to operational efficiency and cost-effectiveness.
What is the heat of reaction of ethylene when form vinyl chloride?
The heat of reaction for the conversion of ethylene (C2H4) to vinyl chloride (C2H3Cl) involves the addition of chlorine to the ethylene molecule. This process typically requires energy input, as it is an endothermic reaction. The specific heat of reaction can vary based on conditions, but it is generally determined through experimental data or thermodynamic calculations. For precise values, consulting thermodynamic tables or specific literature on the reaction is recommended.
What are the driving forces of liquid liquid extraction of acrylic acid using ethyl acetate?
The driving forces of liquid-liquid extraction of acrylic acid using ethyl acetate include differences in solubility and polarity between the two substances. Acrylic acid is more soluble in ethyl acetate due to its polar nature, which allows for efficient extraction. Additionally, the partition coefficient, which reflects the distribution of acrylic acid between the two phases, plays a crucial role in determining the extraction efficiency. Temperature and the presence of other components can also influence the extraction process.
Can you use a ground loop small pump and heat exchanger in the air handler to cool your house?
sounds good. ground loops work and there are sites on the web showing how to and such. > I wanted to put a car radiator in a friends cabin and another in the river out back. A small pump and plastic piping would have done a number on the hot weather. He opted for a large window unit.
According to scientists, the density level of molasses is 1.4 grams per milliliter. In addition, honey and corn syrup have the same density level.
Aims and objectives of pesticides?
The aim is to kill or control pests, with the objective being better conditions in which to live-work- or eat.
What is the nominal wall thickness in a shell or head of vessels?
technically nominal wall thickness refers to pipe wall thickness (average)..if you are referring to shell/hull/fore part of a vessel, the thickness varies depending of type, size, deadweight of the vessel
Side wall cooling calculation for glass tank furnace?
Typically 1000 cubic feet per minute (per linear running foot of the perimeter at the glass line) of air at a static pressure of 4 inches of water column if the requirement is only for the sidewalls. so for a 6 meter by 14 meter furnace the perimeter would be slightly less than 40 meters (131 feet) so the installed cooling would be 131000 CFM (2 blowers of 65000 CFM)
If the crown too is to be cooled a safer calculation would be 1950 cubic feet per minute. It is a trade off. More cooling will give a better life but a lower energy efficiency.
Why does a liquid rise in a capillary tube?
This is due to Surface Tension. The molecules/atoms of the liquid are atrracted by the particles of the solid and thus the liquid rises in the capilliary tube.
How do you make oil out of shale?
You don't make oil from shale, you extract oil from shale. The shale acts like a sponge, sometimes the shale is so porous that the oil can be squeezed or sucked out, otherwise it can be extracted by crushing and heating the shale.
