Incombustible and used in Fire Extinguisher
CCl4
The softness or hardness of a grinding wheel depends upon the type & amount of bonding material used. For general purpose cutter grinding __________ grinding wheel is normally used.
aluminium oxide
Tin based white metals are used, where bearings are subjected to
high pressure & load.
Friction factor for fluid flow in pipe does not depend upon the
pipe length
alloying elements of steel which is hard and ductile
Nickel
alloying elements of steel which is hard but brittle
Chromium
type of bonding which is strongly directional in solids.
Covalent Bond
strongest chemical bond
Covalent bond
Fog is an example of colloidal system of
liquid dispersed in gas.
Chromium molybdenum steel can not be welded using
electrical resistance
Speisses is a mixture of
Arsenides of heavy metals.
Auto collimator is used to check
angle
In troposphere (the weather domain), the temperature ‘t’ at height ‘h’ above the sea level in metres is given by
t = 15 - 0.0065 h
A high pressure boiler generates steam at a pressure greater than
80 kg/cm2
Evaporative cooling process
removes sensible heat and adds latent heat
It is a white powder and is very explosive
RDX - Royal Demolition Explosive / Research Development Explosive
aka cyclonite or hexogen
RDX/ Cyclonite/Hexogen
C3H6N6O6
A flammable toluene derivative, used as a high explosive and in the manufacture of dyestuffs and photographic chemicals.
TNT - Trinitrotoluene
TNT - Trinitrotoluene
C7H5N3O6
is an explosive and toxic crystalline compound frequently used in primers, blasting caps, and fuses. It is sensitive to heat, shock and friction.
Lead Azide
It is a cellulose derivative often used as its sodium salt, sodium carboxymethyl cellulose. It is also used in cosmetic industry as thickener and binder.
CMC = Carboxymethyl cellulose (CMC) or cellulose gum.
Maxwell’s thermodynamic relations applies to the
chemical systems in equilibrium.
relates thermodynamical properties such as enthalpy, entropy and temperature to mechanical properties such as (Pressure or volume) of a system that is chemically in equilibrium wether its reversible o irrevesible.
