Centrifugal PumpsThese (Asdal, 1997)are mechanical devices or equipment that are designed to mechanically pump fluids that is gases and liquids and sometimes slurries from one point to another. They are made of different components arranged in different forms making them to vary in their variety and how they work. These components are; the impeller, the shaft and seal, the motor, the backing plate and the casing. These components work together...

Calculation of Cogging Torque and FrequencyThis section involves finding the maximum magnitude of the cogging torque and its frequency (pulsations per mechanical revolution). In this problem, the cogging torque is the torque ripple, which is produced from the preferred rotor alignment at certain angular positions at zero load. This means that if the stator is not excited. The required calculation is done as shown below. Cogging Torque = the...

Types of Drag and Their DefinitionsDrag (also referred to as air resistance, friction, or fluid resistance) is a force that acts in opposition to any object's relative motion in relation to the surrounding fluid.  A fluid layer (or surface) and a solid surface can both be involved in this phenomenon. The drag force is dependent on velocity, unlike other resistive forces, such as dry friction, which are practically independent of velocity....

SummaryOne of the critical problems that affect the cracking of light water reactors core components is the Irradiation-Assisted Stress corrosion cracking (IASCC).

The fluids used in steering and suspension system needs to be disposed or recycled through trapping, storing and disposing techniques. The fluid needs to be locked and prevented from leaking. It shou...

DiscussionThe materials used in the formation of lightweight roofing are used to provide features for roofing applications. The materials used for the lightweight roofing applications are termed as lightweight based on the specifications and the weight of them. The specifications of the materials are in the ranges of 20 kg per meter. The weight of the materials used for the roofing is only considered when fitted on the roof. The materials wi...

Hydraulic Systems in Concorde1.a) At first there have been 4 Hydraulic structures in the Concorde arrange, yet the RED shape turned into deleted, because it became felt to be trivial. Airbus copied the water managed naming machine (Green, Blue and Yellow weight driven structures) for his or her flying device from Concorde, however the manner that it became pressed for Concorde from the critical fly bearer on earth, the British constructed Come...

Overview of Circular EconomyCircular economy entails a different approach from the past linear economy that was wasteful of resources. Circular economy ensures that resources are kept for a relatively longer period of time. This enables a commodity to be fully utilized even after it is service life has been depleted. The circular economy approach has been adopted recently as a viable platform that enables economical gain. The idea of circular ...

Introduction to Evacuated Solar Tube CollectorA tube solar collector refers to a successive number of glass tubes, connected to a pipe, placed parallel to each other. Air is evacuated from the individual tubes creating a vacuum aspect within them. The vacuum in the tube ensures that the surrounding temperatures are kept at a certain minimum as well as maintaining the loss of thermal heat to the least. As a result of this vacuum, these types of...
