The Lubrizol Corporation makes additives for oils and paints that promote a desirable property in that product (i.e. an oil additive that prevents viscosity breakdown).
How do you calibrate the muffle furnace?
use a reference digital thermometer with a probe that can measure 1800C. actually use 5 probes to measure the different areas inside the chamber...measure then compute for the uncertainties....
Does dredging have anything to do with chemical engineering?
Not really. It deals with pumps which is more of a general engineering application.
There is huge scope for polymers because of thir application in various fields.
eg. biopolymers, manf of appliances, catalyst supports, hydrophilic polymers, in medicines, in surfactants etc.
Why asphalt road look like concrete?
Asphalt roads look similar in nature to concrete because both use an aggregate material consisting of rocks to make up as much as 60% of the volume of the final solid material.
ferroin indicator
No, pennies are made of copper and zinc
Potash is potassium carbonate.
Can PCl5 act as both oxidizing and reducing agent?
The oxidation state of phosphorous in PCl5 is +5.The valence shell has 5 electrons.It
therefore cannot increase its oxidation state more than 5.Therefore PCl5 cannot act as
a reducing agent as it cannot donate electrons.The oxidation state can be decreased to
+3 by gaining electrons. There for PCl5 can act as a oxidizing agent.A example is given
below along with the change in oxidation states of phosphorous.
Why Don't we use odd number of tube passes in Shell and Tube Heat Exchanger?
It is difficult from cleaning point of view. Both end chambers have to be removed so as to clean the heat exchanger with odd nos of passes.
Thanks & Regards

Babu Banarasi Das National Institute of Technology & Management, Lucknow, is an engineering college associated with Uttar Pradesh Technical University. It's ranking is not easilly determined within that university. Established in 1998, many, but not all, of its degree programs have been accredited by the Indian National Board of Accreditation.

Thermosiphon(alt. thermosyphon) refers to a method of passive heat exchange based on natural convection, which circulates liquid without the necessity of a mechanical pump. This circulation can either be open-loop, as when liquid in a holding tank is passed in one direction via a heated transfer tube mounted at the bottom of the tank to a distribution point - even one mounted above the originating tank - or it can be a vertical closed-loop circuit with return to the original vessel. Its intended purpose is to simplify the pumping of liquid and/or heat transfer, by avoiding the cost and complexity of a conventional liquid pump.

You can see this assembly mounted on chemical agitated reactors, they provide cooling to agitators.
Basically principle is density difference... cold fluid has more density than cold one.. this is reason for motion of fluid. eg. solar heaters
How do you produce ceramic tiles?
I need to know how to produce ceramic tiles. specially, the updated technology of kilns of single firing ceramic tiles. Need to know how to solve the problems.
When the efficiency of wet cooling tower is lower than dry cooling tower?
1. In wet cooling tower Two phase flow heat trasfer 2. To remove sensible heat from water is very critical 3.It depends on water droplet size ,fills design,orientastion and climatical condition.

What is the Three Reservoir Problem?
This is a classic problem in hydraulic engineering. Three reservoirs are connected by pipes. All the reservoirs have surfaces at different elevations.
Given the height each reservoir and pressure loss in each leg of the pipe network, liquid will either flow into or out of each reservoir.
If you apply the Bernoulli equation from the surface of each reservoir to the pipe junction, you end up with three nonlinear equations in four unknowns (the flowrates in each leg of the piping network and the total pressure head at the junction). An additional equation is supplied by applying the Continuity Law at the pipe junction (i.e. the sum of all flowrates at the junction is zero if there is no outflow).
This now gives four equations in four unknowns; no analytical solution is possible. You can solve the equations iteratively, however, using a tool like Excel. See the spreadsheet in the related link for an example
What is the ranking on engineering levels?
Engineering levels are pretty simple: * Level 1 or Entry level or Graduate level * Level 2 or Engineer * Level 3 or Senior Engineer / Becoming a Chartered * Level 4 or Lead Engineer / Chartered Status + postgrad * Level 5 or Chief Engineer / Chartered Status + Masters Eng or Business or PHD Each step takes 2 - 4 years depending on the individual.
Role of trimethyl silyl azide?
Trimethylsilyl azide is often used as a safer replacement for hydrazoic acid in organic synthesis. An example is the synthesis of Oseltamivir (ie Tamiflu).
It equals one kilpod.
