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...

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...

Essay 2, Autoclave

The destruction of microorganisms is indispensable as far as medical sterilization is concerned. It is a global procedure for killing all known forms of microbial life. Autoclaves provide a solution to effectively sterilizing medical items. The system uses the pressure-temperature principle to achieve the desired objectives effectively and efficiently at different levels; temperature and pressure. In order to clean items, moist steam under desired pressure per square inch (psi) is used to kill all microbial organisms present. The bodies come into contact with direct steam that penetrates the endospores thus effectively killing them.
When the pressure of gas increases, Continue reading...

Introduction

In the contemporary times, there has been a significant increase in global temperatures. Various natural and human factors have contributed in bringing considerable climatic changes all around the world. Industrial development, agricultural advancement, and progression in transportation system are largely blamed for the production of natural greenhouse gases. In addition, the chlorofluorocarbons and related pollutants also supplement the thermal blanket. For these reasons, it is commonly accepted that the increase in global temperatures and subsequent climate changes are the outcomes of increased masses of greenhouse gases. Climate changes that are observable and apparent include rise in Continue reading...

Abstract

Radiation cataractogenesis (RCG) is deterministic. It does not occur below a minimum threshold dose. RCG is generally believed as dose-related. Sliney (1986) believed that its severity is also dose-related. The severity increased and the latency decreased as radiation dose increased above that threshold. The lens of the eye is nonvascular and is known to experience no cell loss over its lifetime, indicating that any damage to its cells will not result to the removal of these cells for lack of existing mechanism. Three induction mechanisms were explored (direct, indirect, and oxidative, which separately creates oxidative stress inside the lens Continue reading...

Analog and digital signals, basically, differ in their graphs of voltage versus time. Analog signals have a continuous signal function with respect to time (Angoletta, 2014). The signal here can be sound, light, temperature, pressure, etc. The signals have smooth continuous changes similar to an analog watch. On the other hand, digital signals have a discrete (taking only binary values 0 and 1) function with respect to time. The signals have determined levels such as the case of the digital clock where time can only take account of 0 to 9.
The advantages of using analog versus digital signals Continue reading...

V-2 Rocket

Abstract
The world of rockets includes missiles, aircraft, spacecraft, or other vehicles that gets plunges from the engine of a rocket. Studies show that the first rocket or the V2 missile that could flew high enough to outer space in 1942. The Germans first used the V2 rocket and history shows that their knowledge of missiles and rockets surpassed others in that era. Rocket engine exhaust comes mainly from the propellants that come from inside the rocket before its use. Rocket engines operate based on reactions and actions. Researches show that rocket engines often thrust rockets ahead by ejecting Continue reading...
