What does well abandonment mean? Well abandonment is an often misused term. “Well abandonment” generally means abandonment through filling or sealing a well so as to prevent the well, including the annular space outside the casing, from being a conduit or channel that allows the vertical movement of water—either up or down. What is well […]
What is thermodynamic equilibrium Class 11?
What is thermodynamic equilibrium Class 11? In thermodynamic equilibrium all the thermodynamic processes of the system remain constant with time. All the macroscopic properties like free energy change or work are remaining the same and a system in isolated condition. What are the types of thermodynamic equilibrium? When the state variables do not change with […]
Which description represents the meaning of the alphabet of lines?
Which description represents the meaning of the alphabet of lines? The Alphabet of Lines is a list of line symbols that engineers use in technical drawings to communicate specific shapes, sizes or surfaces. The lines and symbols used in the Alphabet of Lines are universal, which means engineers around the world use and understand them. […]
What are the processes of Otto cycle?
What are the processes of Otto cycle? The Otto cycle consists of isentropic compression, heat addition at constant volume, isentropic expansion, and rejection of heat at constant volume. What are the major processes in the air-standard Otto cycle? The Otto cycle is an air-standard cycle which approximates the processes in petrol or diesel engines. It […]
What are examples of engineering controls?
What are examples of engineering controls? Engineering controls protect workers by removing hazardous conditions or by placing a barrier between the worker and the hazard. Examples include local exhaust ventilation to capture and remove airborne emissions or machine guards to shield the worker. What are the three engineering controls? Engineering controls consist of a variety […]
What is the main role of engineer?
What is the main role of engineer? Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. What statement best describes what engineers do? Explanation: The engineers […]

What is the difference between yield stress and proof stress?
What is the difference between yield stress and proof stress? The yield strength or yield stress is a material property and is the stress corresponding to the yield point at which the material begins to deform plastically. In such a case, the offset yield point (or proof stress) is taken as the stress at which […]
How does high density altitude affect performance?
How does high density altitude affect performance? Because high density altitude has a detrimental impact on aircraft performance. It reduces lift and impairs propeller efficiency, reducing thrust as a result. High density altitude can also decrease the engine’s power output. How does density altitude affect stall speed? As air density decreases with increasing altitude, more […]
What is the equilibrium wage in this labor market?
What is the equilibrium wage in this labor market? The equilibrium market wage rate is at the intersection of the supply and demand for labour. Employees are hired up to the point where the extra cost of hiring an employee is equal to the extra sales revenue from selling their output. Why does the Monopsonist […]
