Abstract

Pump performance curve refers to the relationship between a pipe, the flow of the liquid and efficiency levels. This paper shows the procedure of calculating a pump performance curve. It talks about how it is important to have the right type of pump for the experiment. Centrifugal pump is the most common type because of its numerous advantages, for example, it is cheap and occupies a small space. Furthermore, it does not emit any noise when in operation and it is simple to use. The paper also talks about model development of the efficiency and the process of calculating Continue reading...

Final Report

Part A. Energy Audit
Introduction
Initiatives to decrease energy consumption have largely focused on reducing domestic electricity. Using data from a domestic electricity bill can provide clear information about the high cost of one home’s electricity consumption. Furthermore, conducting an energy audit can help one discern which appliances are the most intensive. Analyzing the rooms and appliances that consume the most power will help direct plans to reduce electricity consumption. The following energy audit will provide the background data to help implement an energy reduction plan which will in turn have a positive impact economically by helping the Continue reading...

1.0 Abstract
The report is divided into two major sections. The first section of the report deals with a discussion about fundamental physical quantities together with their SI units. The quantities highlighted in the report include Mass, length, time, temperature and plane angle. A discussion of the derived physical quantities together with their units has also been presented in clear detail. The second part of the report focuses on providing a discussion of two machines that apply thermodynamics and are used in oil and gas industry. The machines identified to apply Continue reading...

Abstract

The primary purpose of this research is to illustrate the best practices which need to be followed in order to minimize the risks of leakages and mishaps resulting from the leakages. As the demand of LNG is on constant rise, the need of the hour is to prevent the leakages which may result either from the technical glitch or lack of adherence to the standard processes to be followed as recommended by the best practices through industrial standard. It is known that the Liquefied Natural Gas (LNG) is not as harmful as Continue reading...

Since the time when man possessed fire, the vast majority of fires were caused by humans. In the excavations of ancient cities, archaeologists found the causes of numerous fires in Bukhara, Samarkand, Alexandria, Baghdad, and Rome. Because fire is so destructive, mankind began gradually to organize fire services, the purpose of which was to prevent fires and to fight fires.
The first fire pump was created in Ancient Greece in year 200 BC. Greece inventor Heron invented a rotary tube, and the pump was very helpful in fighting fires.The relationship between man and fire was reflected in Babylonian, Sumerian, Continue reading...

Objective

The aim is to have a robot design that would be used in the detection of fire existence. It will be a useful system that will be instrumental in detecting fire breaks and having strategies to put off the fires in advance. The aim of the research is to have a fire robot that would be multi-sensor and would be useful in fighting fire in every-day life. In the design, the firefighting robot will make use of flame detectors. The firefighting methods and procedures will be programmed with the use of sensor-based methods and procedures. There are thermistors/flame sensors Continue reading...

Variable Frequency Drives

Introduction
VFD is a system of control rotor speed asynchronous (or synchronous) motor. It consists of the motor and the inverter. Frequency converter (inverter) is a device consisting of a rectifier (DC bridge), which converts AC power to DC power, and an inverter (converter, sometimes with PWM), which converts direct current into alternating required frequency and amplitude. Output thyristors (GTO) or IGBT transistors provide the necessary current to power the motor. To avoid the inverter overloading with great length between the inverter and the feeder chokes are put. To reduce to reduce EMI it is being used EMC-filter.
With Continue reading...

ABSTRACT

Cardiomyopathy is a heart disease characterized by stiffening and hypertrophy of the musculature of the heart followed by scarring. It deprives the heart from the flexibility required in the muscles to pump the blood sufficiently leading to heart failure. There are four major types of cardiomyopathy and it can be acquired or congenital. Latter usually unpreventable and can only be controlled. Usual symptoms are shortness of breath, easy fatigability, edema of limbs and venous engorgement. Clinical as well as radiological evidence is required for its diagnosis. Surgical interventions are available to treat cardiomyopathy and besides pharmacotherapy, physical activity and 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...

Heart muscles require oxygen-rich blood for its nourishment. and coronary arteries in our body provide the oxygen-rich blood to the heart. Sometimes due to formation of plaques of different sizes as a result of deposition of fatty matter, calcium, protein, and inflammatory cells within the arteries, the coronary arteries become narrow and blood cannot flow normally. When such plaques restrict the flow of blood within the artery the heart muscles cannot get the required oxygen through the blood, if the blood flow is not restored quickly the section of the heart muscles begins to die in want of oxygen. ( Continue reading...
