What does it mean to dimension a drawing? Definition Dimensioning is the process of specifying part’ s information by using of lines, number, symbols and notes . Lines to be used are always thin continuous line. 2. Symbol or abbreviation commonly found in a drawing are – “ diameter ” is represented by a symbol […]

What is the flow of water through a cell membrane called? osmosis What is the movement of water down a concentration gradient? Osmosis is the movement of water through a semipermeable membrane according to the concentration gradient of water across the membrane, which is inversely proportional to the concentration of solutes. When water molecules move […]

What is integrity in terms of information security? In the world of information security, integrity refers to the accuracy and completeness of data. Security controls focused on integrity are designed to prevent data from being modified or misused by an unauthorized party. How do you ensure confidentiality and integrity and availability? Putting Confidentiality into Practice […]

How do you calculate flow rate through a pipe? If the liquid is flowing through a pipe, the area is A = πr2, where r is the radius of the pipe. For a rectangle, the area is A = wh where w is the width, and h is the height. The flow rate can be […]

What are the NC motion control systems? In NC, there are three basic types of motion control system (Point-to-point, Straight cut and Contouring). Point-to-point systems represent the lowest level of motion control between the tool and workpiece. What are the basic components of NC system? A computer numerical control (CNC) system consists of three basic […]

What is the force that attracts all objects to each other? Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the […]

What is Gauss Seidel iteration method? Gauss–Seidel method is an iterative method to solve a set of linear equations and very much similar to Jacobi’s method. The name successive displacement is because the second unknown is determined from the first unknown in the current iteration, the third unknown is determined from the first and second […]

Does preheating fuel increase efficiency? It is known that preheating gasoline or other fuel for internal combustion engines can produce more efficient vaporization and higher combustion efficiency and engine performance than cold fuel. What is regenerative air preheater? Regenerative type of air preheater:- Tri sector regenerative preheater is commonly used in power plant. this design […]

Which lubrication system is used in 2 stroke engine? petroil mixture What is the primary cause of pollution from a two stroke engine? Two-stroke engines produce a lot of pollution because the fuel-air mixture in them gets contaminated with the engine’s lubricating oils. This allows fuel to enter the combustion chamber when the exhaust port […]

How is activation energy related to the energy of reaction? Activation energy and reaction rate The activation energy of a chemical reaction is closely related to its rate. Specifically, the higher the activation energy, the slower the chemical reaction will be. The higher the barrier is, the fewer molecules that will have enough energy to […]
