The factors that are affected by number of tubes in shell and tube heat exchanger is the rate of heat transfer and flow rate.

The standard size of the Petroleum Refinery is in the multiples of 3Million tonnes per annum or lakh barrels of crude.

Dimedone is synthesized from mesityl oxide and diethyl malonate .

Well, all you do is invite the friends you want to be in the group chat.

Very depend on the application, concentric pipe had lower pressure drop and better flow distribution. However, in many case, eccentric pipe reducer is installed on propose to allow liquid drainage from reducing in horizontal pipe.

Water wells are a prehistoric advance. A precise time and location are unlikely to ever be discovered.

The exact answer is needed because flow metering systems uses water at 60 deg f to calculate fluid specific gravity from fluid density. SG= fluid density Lb/f3 / water density lb/f3 at 60 deg f.

Scientists work together in a way with engineers by thinking the solution and the engineers execute it so basically the scientist thinks it the engineer does it.But some times the ideas of scientists are so weird that they become hard for the engineers to do.

1- It doesn't need a power source or fuel.

2- its cost is relatively low.

3- it is available for several fluid.

4- it can be used for both vertical and horizontal directions.

SILVER SULFADIAZINE is a sulfonamide antibiotic. It is used on the skin for second or third degree burns. It helps to prevent or treat serious infection.

No. That requires a special filter.

Inefficiencies in a mechanical device related to parts rubbing together such that kinetic energy is turned into heat energy.

Depends on which side of the planet your on and what tensile strength your seeking and if your following safe water drinking act of 1974 or if you soldering vent, soil or drainage or heating or potable water supply There is tin / lead alloy depending on composition

There it tin and antimony Tin and silver content Are you talking about Hard solder commonly known as brazing? Check with the AWS to give you more information of the CDA

Low tox drilling mud is water based.

The main requirement for an alloy system to respond to age-hardening is a significant decrease in solid solubility of one or more of the alloying elements with decreasing temperature.

It may be recovered for use in construction additives and there also applications like fertilizer. Reuse plan is very depending on the availability of such carbonate sludge, concentration and the species of other impurities.

Therminol 66 is a heat transfer fluid with a low pour point, and therefore is unlikely to be encountered in a solid form that would require melting. Furthermore, Therminol 66 like other heater transfer fluids is expensive and should not be burned if at all possible.

For isotropic materials, Rubber - very close to 0.5

A capping agent is a strongly absorbed monolayer of usually organic molecules used to aid stabiliztion of nanoparticles....

Ceramic products may break.

I do feel bad about answering this one, it is quite simple. Find the volume, multiply it by the atom density, then divide by avogadro's number, and finally, multiple by the molecular weight of boron.

Assuming this wafer is cylindrical.

Find the volume

Volume = pi*D^2/4*thickness
3.14*(30cm)^2/4*.07cm= 49.48 cm^3

Multiply it by the atom density
Volume*rho.atom
49.48 cm^3*1 X 10^16 atoms/cm^3= 4.948 X 10^17 atoms boron

Then divide by Avogadro's number
Atom/N.a= mol
4.948 X 10^17 atoms/(6.022 141 79(30) × 1023 atoms/mol)= 8.217 X 10^-7 mol

Finally, multiple by the molecular weight of boron.
MW.B = 10.811 g/mol
8.217 X 10^-7 mol*10.811 g/mol= 8.883 X 10^-6 grams = 8.883 micrograms

Yes, but it will depend on what do you want to filter.

For example, in metallocenic polymer synthesis, at the end of the polymerization the polymer is precipitated from a toluene solution and then filtrated using a vacuum filter.

As most plastics used in specimen tubes will melt if sterilized with heat the plastic tubes are normally single use

Yes, freon can indeed cause corrosion. Freon leaks in vehicles can corrode surrounding parts and components in the car over time.

Zero, do not mix gasoline and diesel together unless you have a lot of money and like to fix things. <><><> For more information see the answer to the Related Questionshown below.
