Equilibrium Moisture Content
Equilibrium moisture content (EMC) is the amount of water present in the solid, which exerts a vapour pressure equal to the vapour pressure of atmospheres surrounding it.
Pharmaceutical Engineering
Mixing of soluble Solids in Liquids
Mixing devices are technically called an impeller. Impellers are classified on the basis of the sample and pitch of the blades that are attached to the central shaft.
Particle Size Distribution of a powder- Sieving Method
Sieving method directly gives weight distribution analysis. From the data dsieve can be calculated. Sieve diameter is defined as the diameter of a sphere that passes through the sieve aperture as the asymmetric particle.
Radiation constant of metal cylinder
As the metal cylinder is freely suspended without any contact with the metal the heat loss through conduction is minimum. For this reason, the metal cylinder is placed on a glass tripod stand. Thus heat loss by radiation is highlighted
Size reduction of material using ball mill
The ball mill works on the principle of impact between the rapidly moving balls and the materials .Both the balls and the sample are enclosed in a hollow cylinder. At low speeds the ball rolled over each other and attrition takes place
Determination of Humidity – Psychometric Method
Humidity is defined as the ratio of mass of water present in the air to the mass of dry air.
Effect of Materials Related Factors on Filtration Rate-Calcium Carbonate Suspension
Filtration may be defined as a process of separation of solids from a fluid by passing the same through a porous medium that retains the solids, but allows the fluid to pass through.
Determination of Humidity by Dew Point Method
Dew point is defined as the temperature to which the mixture of air water vapour must be cooled at constant humidity to become saturated.
Effect of Process Related Factors on Filtration Rate
Filtration may be defined as a process of separation of solids from a fluid by passing the same through a porous medium that retains the solids, but allows the fluid to pass through.
Crystallization by shock cooling
Crystallization is the spontaneous arrangement of the particles into a repetitive orderly array,i.e., regular geometric pattern. Crystals are commonly obtained from liquid state.
