Which thyristor is commonly used motor speed control? Half converter, semi converter, full converter and dual converter are some of the thyristor based circuits which are used for speed control of DC motor. This paper studies different speed control techniques of DC motor and makes a comparative study of different converter based speed controller techniques. […]
What is the boiling temperature of petrol *?
What is the boiling temperature of petrol *? From the chemical composition viewpoint, petrol is a blend of hydrocarbons between C4 and C11, with boiling points between 25 and 210°C and in which we can find all types of hydrocarbons: paraffins, isoparaffins, olefins, aromatics, naphthenes, etc. What is the boiling point of gasoline? about 200 […]
What hydraulic system contains valves?
What hydraulic system contains valves? A hydraulic valve properly directs the flow of a liquid medium, usually oil, through your hydraulic system. Hydraulic valves are subdivided into three main categories: directional control valves, pressure control valves and flow control valves. All valves operate a different function in the hydraulic system. What is the function of […]
How can a JetPack fly?
How can a JetPack fly? The pilot controls the JetPack by “vectoring the entire engine, rather than just vectoring thrust”, says the company. “This is how we achieve such great manoeuvrability and speed control.” Both types can be flown under FAA rules, under certain conditions, without a pilot’s licence as an ultralight vehicle. How hard […]
Should you wear gloves when using a pillar drill?
Which corrosion is one of the most destructive and intense forms of corrosion?
Which corrosion is one of the most destructive and intense forms of corrosion? Pitting Which out of dry and wet corrosion is more dangerous and why? Dry corrosion or oxidation occurs when oxygen in the air reacts with metal without the presence of a liquid. Typically, dry corrosion is not as detrimental as wet corrosion, […]
How friction is useful to us?
How friction is useful to us? Friction can be a useful force because it prevents our shoes slipping on the pavement when we walk and stops car tyres skidding on the road. When you walk, friction is caused between the tread on shoes and the ground. This friction acts to grip the ground and prevent […]
Which is a critical advantage of plasma enhanced CVD?
Which is a critical advantage of plasma enhanced CVD? PECVD has many advantages over conventional CVD methods, including low deposition temperature, high purity, good step coverage and easy control of reaction parameters (Maeda and Watanabe, 2005). High-quality thin films of TiOi can be formed using CVD. What is CVD and PVD? PVD, or physical vapor […]
What is meant by plant location and plant layout?
What is meant by plant location and plant layout? It may be defined as a technique of locating machines, processes and plant services within the factory so as to achieve the right quantity and quality of output at the lowest possible cost of manufacturing. Plant layout refers to the arrangement of physical facilities such as […]
What is considered process piping?
What is considered process piping? What is Process Piping? Process Piping is a unique technique used to convert chemicals, gases, and liquids into tangible and valuable products. In a nutshell, process piping incorporates any pipes excluded from a building’s mechanical systems and instead channeled towards the production of a specified product. What is plumbing process? […]
