Their basic design consists of four elements: Rectifier: the working principle of rectifier is changing the incoming alternating current (AC) supply to direct current (DC). Different designs are available and these are selected according to the performance required of the variable frequency drive.
Fire safety design - Designing Buildings Wiki - Share your construction industry knowledge. Buildings need to be designed to offer an acceptable level of fire safety and minimise the risks from heat and smoke. The primary objective is to reduce to within acceptable limits the potential for death or injury to the occupants of a building and others who may become involved, such as the fire and ...

24-08-2020· How do fire extinguishers work? Inside, a fire extinguisher is quite like a giant aerosol can, often with two different substances inside.One of them is a solid, liquid, or gas substance for fighting the fire. The other one is called a propellant and is a pressurized chemical that makes the fire-fighting substance come out when you press the extinguisher handle.
An internal combustion engine (ICE) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine.
Abstract. The historical development and application of reinforced concrete structure are briefly introduced. Comparing with the structure made of one single material, e.g. steel, brick, or timber, reinforced concrete structure is mainly composed of two materials with much different properties, and the characteristics, advantages, and disadvantages of it are analyzed.
01-09-2013· Working principle of a vortex tube Based on the discussions above, the flow behaviour inside a vortex tube is summarised in detail as shown in Figs. 2 and 3 . This basic on which the temperature separation in a vortex tube can be explained is as follows: When compressed air is injected into the tube from the tangential inlet, it forms a highly vortical flow and moves to the end of the tube.
Construction (Design and Management) Regulations 2015. A principal designer is a designer who is an organisation or individual (on smaller projects) appointed by the client to take control of the pre-construction phase of any project involving more than one contractor.. Principal designers have an important role in influencing how risks to health and safety are managed throughout a project.
The principle on which the air-cooler works is as follows- Water, when evaporates it needs heat called 'latent heat of evaporation'. In the cooler the water that is sprayed over the pads when evaporates takes the required latent heat from the atmospheric air surrounding them which on losing its heat cools down.
Working : (i) DOL starter wiring connection with start and stop buttons are shown in the above figure (1). Between the mains supply terminals and motor terminals the DOL starter main terminals are connected and with the two terminals of the three-phase power supply …

Design flexibility. Egress route and fire/smoke barrier placement becomes less restrictive since early fire control minimizes demand on these systems. Many fire and building codes will permit design and operations flexibility based on the presence of a fire sprinkler system. Enhanced security.

This construction has been conceived merely to explain the working of SCR, otherwise in physical shape the SCR has four solid layers of P-N-P-N type only. Now we can see that the two transistors are connected in such a manner that the collector of Q 1 is connected to the base of Q 2 i.e. the output collector current of Q t becomes the base current for Q 2 .
13-01-2019· Before we can explain the working principle of a DC generator, we need to cover the basics of generators.. There are two types of generators – DC generators and AC generators. Both DC and AC generators convert mechanical power to electrical power.A DC generator produces direct power, while an AC generator produces alternating power.
