The document defines various terms used in the sugar industry and describes the processes involved. It discusses the mill house where cane is prepared and milled to extract mixed juice. It then describes the boiling house where the juice undergoes clarification, evaporation to produce syrup, sulphitation, boiling in pans to produce massecuite, and centrifuging to separate sugar crystals from molasses. A flow chart illustrates the double sulphitation process from cane preparation through sugar production and byproducts.
The document discusses various types of size reduction equipment used in mining and manufacturing processes. It describes crushers which use compression forces to reduce large solid materials into smaller particles ranging from 150-250mm. Specific crushers covered include jaw, gyratory, and roll crushers. Grinders further reduce particle sizes down to 74-350um using different grinding mechanisms like hammer mills, ball mills, and rolling compression mills. Ultra fine grinders can process materials into micron-sized particles from 1-50um using technologies such as agitated mills or fluid energy mills. Cutting machines also aid size reduction from 2-10mm using knife, cutter, or slitter tools.
Forced circulation evaporators use pumps to circulate liquid through tubes at high pressure. This prevents boiling and elevates the boiling point. When the liquid exits the tubes, the sudden pressure drop causes flashing to vapor. This forced circulation and flashing leads to more efficient evaporation. Forced circulation evaporators are useful for evaporating viscous or heat-sensitive substances since the pumping action prevents localized overheating and the rapid flow reduces thermal damage. However, they require more energy due to the power needed to drive the pumps.
Newton's law of viscosity states that shear stress is directly proportional to velocity gradient. Fluids that obey this law are called Newtonian fluids, while those that do not are non-Newtonian fluids. Non-Newtonian fluids can be divided into two categories based on whether their shear stress is dependent or independent of time. Examples of time-independent non-Newtonian fluids that have shear stress independent of time include Bingham plastics, pseudoplastics, and dilatants. Time-dependent non-Newtonian fluids that have shear stress dependent on time include thixotropics, rheopectics, and viscoelastic fluids.

Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...PriyankaKilaniya
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.
Height and depth gauge linear metrology.pdfq30122000
Height gauges may also be used to measure the height of an object by using the underside of the scriber as the datum. The datum may be permanently fixed or the height gauge may have provision to adjust the scale, this is done by sliding the scale vertically along the body of the height gauge by turning a fine feed screw at the top of the gauge; then with the scriber set to the same level as the base, the scale can be matched to it. This adjustment allows different scribers or probes to be used, as well as adjusting for any errors in a damaged or resharpened probe.
