Abstract

In the laboratory assignment, the experimental investigation of the distillation process is performed. The mixture of dichloromethane and trichloroethylene was separated using the glass distillation column. The influence of power input on temperatures and column flow rate was investigated. Apparently, the power input increases the efficiency of the process. The experiment had three main tasks: study of the variation of the pressure drop, application of refractometer as an express method of binary mixture composition analysis, and estimation of the column efficiency.
It has been proven that the boil-up rate is directly proportional to pressure drop. Although there is some Continue reading...

Industrial Applications of Membrane Separation Processes

Abstract
Membrane separation processes are widely used in various industrial operations to separate the desired components from the mixture. The membrane that is used depends on the type of process employed in the system. The membrane also varies in size and materials. This paper focused on the industrial application of ultrafiltration, microfiltration, and pervaporation. Ultrafiltration is effectively used in recovery of milk proteins in whey and reduction of waste. The process of microfiltration is successfully use in solids removal and disinfection of wastewaster. Pervaporation shows good result in the removal of volatile organic compounds in contaminated water.

Ice cream is the dessert which is admired by every age of people. The cooling and chilling effect of ice cream which melts down the taste buds of the tongue to the stomach is cherishable and soothing. Most of the people are ice cream lovers, and they are ready to have one at any time. However, few are aware of the fact regarding its production.
Ice cream basically consists of the milk, sometimes eggs, sugar and cream in the form of a mixture. This mixture is churned while keeping it on the freezing temperature. Hence, the ice cream is Continue reading...

Making ice cream requires a few basic steps. Starting with simplest, vanilla flavored ice cream can be tried. For it one will need four eggs, using only the yolk. A hundred grams of caster sugar is needed, with one cup of whole milk, two cups of heavy cream-full fat, one vanilla pod to extract or simple use vanilla extract and a little bit of salt to taste. The utensils required include a large heavy bowl, a whisk, a wooden spoon, measuring cups, a strainer, and an ice Continue reading...

Introduction:

Agent (A) is forensic technician with the forensic team in crime central Tallahassee; she has been with the team for 25 years. Who collects different types of evidence that a crime scene investigators looks for when observing and processing a crime scene that can be used later for further investigations and court proceedings. There are testimonies that can be collected from any witnesses, items that are gathered at the crime scene which are considered physical evidence, biological evidence like fingerprints and trace evidence which may be small but could be very important for the process of figuring out what Continue reading...

Back titration of Calcium Carbonate with Sodium Hydroxide.

Introduction
Here the amount of Calcium Carbonate is asked and because it is an insoluble salt "back titration" is used. Titration is a method which it's another name is volumetric method, in this method a reactant is used to bring a reaction to endpoint. In this method, one sample (unknown) value is determined by a standard (known) value.
But "back titration" is needed because here Calcium Carbonate is an insoluble salt and it's not possible to calculate its amount by direct titration.
In this experiment first calcium carbonate was reacted with an excess known hydrochloric acid and the unreacted Continue reading...

Concrete is a composite material made up of a mixture of aggregate, Portland cement, sand and water. Upon heating the mixture to high temperatures up to 1600oC in a rotary kiln, the mixture recombines and gains strength . The history of concrete dates back to 6500 BC in northern Syria. Other constructions made of concrete were also found by the archaeologists in Greece, China, Middle East and the Roman Empire in the ancient times. Concrete finds its uses in the construction of buildings, monuments, statues, roads, sewer systems, pumps, dams and many others. The properties of concrete depend upon its Continue reading...

a) From Marpol identify the requirements for the disposal of machinery space bilges.
Marpol 73/78 is the International Convention for the Prevention of Pollution from Ships, 1973 as modified by the Protocol of 1978. ("Marpol" is short for marine pollution and 73/78 short for the years 1973 and 1978.)
“According to Annex I of MARPOL 73/78, and more precisely Chapter 2, Regulation 9, the requirements for the disposal for a ship of 400 tons gross tonnage and above other than an oil tanker and for machinery space bilges excluding cargo pump-room bilges of an oil tanker unless mixed with Continue reading...

Abstract
This paper explores the sports nutrition, sports diet and respective supplements. Sports nutrition is a general term comprising everything related with products manufactured mainly for people doing sport. The main aim of such nutrition is improving the athlete’s performance and increasing endurance. Sports nutrition is not doping, but a rather a complex of easily digesting and highly nutritious elements. Any diet should consist of three main elements: carbohydrates responsible for providing energy, liquid preventing body from heat collapse, proteins maintaining muscle mass, fats, vitamins and minerals. In order to make sports nutrition the most efficient, the diet Continue reading...

Abstract

Three tests were made on the kerosene sample: (a) determining hydrogen content by Nuclear Magnetic Resonance [NMR], (b) determination of viscosity by U-tube viscometer, and (c) flash point determination by Pensky-Marten closed-cup tester. Results suggest that the kerosene sample has 13.73% hydrogen content, 7.706 mm2/s kinematic viscosity at -20°C (extrapolated using Sutherland Viscosity Law), and 52-53°C flash point. These parameters characterized the kerosene sample as aviation fuel in terms of heating value, degree of saturation, pressure drop in fuel lines, pumping characteristics and safe handling. All parameters passed the standards derived from aviation literature. These parameters could Continue reading...
