What does application of centrifugal air compressor lead to? A centrifugal compressor imparts kinetic energy into the airstream by increasing the velocity of the air using a rotating element and then converts this kinetic energy into potential energy in the form of pressure. How do centrifugal compressors work? A centrifugal compressor is a type of […]
What causes residual stress in welding?
What causes residual stress in welding? Welding residual stresses are caused by differential thermal expansion and contraction of the weld metal and parent material. This is illustrated in Fig. 7.5 for longitudinal residual stresses (transverse residual stresses are also induced, although these generally have compressive and tensile zones within the weld). What are residual stresses […]
What are the three types of communication protocols?
What are the three types of communication protocols? These are: Transmission Control Protocol (TCP) Internet Protocol (IP) User Datagram Protocol (UDP) Post office Protocol (POP) Simple mail transport Protocol (SMTP) File Transfer Protocol (FTP) Hyper Text Transfer Protocol (HTTP) Hyper Text Transfer Protocol Secure (HTTPS) What are protocols Name any 3 examples of protocols used […]
What are the macronutrients and their functions to the body?
What are the macronutrients and their functions to the body? Macros are macronutrients. Your body needs these nutrients in larger amounts in order to function properly as macro means large. In addition, all of these nutrients provide your body with energy measured in the form of calories or kcals. There are three types of macronutrients: […]
Which of the following causes stress concentration?
Which of the following causes stress concentration? Stress concentrations occur when there are irregularities in the geometry or material of a structural component that cause an interruption to the flow of stress. This arises from such details as holes, grooves, notches and fillets. Stress concentrations may also occur from accidental damage such as nicks and […]
What is mgso4 used for in chemistry?
What is mgso4 used for in chemistry? Magnesium sulfate is an inorganic salt (chemical compound) containing magnesium, sulfur and oxygen, with the formula MgSO4. It is often encountered as the heptahydrate sulfate mineral epsomite (MgSO4ยท7H2O), commonly called Epsom salt. Anhydrous magnesium sulfate is used as a drying agent. What is magnesium sulfate used for in […]
How does the temperature of the gas relate to the motion of the particles?
How does the temperature of the gas relate to the motion of the particles? Temperature is related to particle motion because temperature increases the motion of particles when it is applied to an object. When you add thermal energy to an object, the particles either move faster (increased kinetic energy) or spread farther apart,(increased potential […]
What is data in terms of database?
What is data in terms of database? Data, in the context of databases, refers to all the single items that are stored in a database, either individually or as a set. Data in a database is primarily stored in database tables, which are organized into columns that dictate the data types stored therein. What are […]
What is the process of logistics?
What is the process of logistics? Logistics is the process of planning and executing the efficient transportation and storage of goods from the point of origin to the point of consumption. The goal of logistics is to meet customer requirements in a timely, cost-effective manner. FedEx, UPS and DHL are well-known logistics providers. What is […]
What is collimation method?
What is collimation method? The collimation method is the height-of-instrument method of leveling whereby fore-and-aft readings are made on a leveling staff by an instrument placed intermediately so that the rise or fall between the fore station and the back station is shown by a change in the staff reading. See Also: rise and fall. […]
