What are examples of reduce reuse and recycle? Refill a water bottle with water from home instead of buying a new one. Update your computer rather than throwing it out and getting a replacement. Ditch plastic bags and choose reusable, environmentally-friendly bags instead. What are three examples of items that can not be recycled? Non-recyclable […]
How is ethylene oxide formed?
How is ethylene oxide formed? Ethylene oxide can be produced by reacting oxygen (O2) and ethylene (C2H4) at temperatures of 200 – 300°C and pressures of 10 – 20 bara. The typical yield of this reaction is up to 80 – 90%. Is Ethylene Oxide an oxidizer? Historically, the most commonly used type of equipment […]
Why is measurement important in welding?
Why is measurement important in welding? Several welding projects require you to understand, calculate and measure welds at different angles accurately. Moderate knowledge of geometrical measurements will make it easier for you to connect metals together while advanced knowledge will make it possible to work on complex projects. Which of the following is the most […]
Why counter flow heat exchanger is more efficient?
Why counter flow heat exchanger is more efficient? Counter flow heat exchangers are inherently more efficient than parallel flow heat exchangers because they create a more uniform temperature difference between the fluids, over the entire length of the fluid path. For example, one fluid may make 2 passes, the other 4 passes. How does a […]
What is the divide and conquer approach to problem solving?
What is the divide and conquer approach to problem solving? A divide-and-conquer algorithm recursively breaks down a problem into two or more sub-problems of the same or related type, until these become simple enough to be solved directly. The solutions to the sub-problems are then combined to give a solution to the original problem. How […]

What are the types of electrical loads?
What are the types of electrical loads? Three basic types of loads exist in circuits: capacitive loads, inductive loads and resistive loads. These differ in how they consume power in an alternating current (AC) setup. Capacitive, inductive and resistive load types correspond loosely to lighting, mechanical and heating loads. What is an inductive load? Reactive/Inductive […]
What are the 8 periods of development?
What are the 8 periods of development? Developmentalists often break the lifespan into eight stages: Prenatal Development. Infancy and Toddlerhood. Early Childhood. Middle Childhood. Adolescence. Early Adulthood. Middle Adulthood. Late Adulthood. What are the 7 stages of development? There are seven stages a human moves through during his or her life span. These stages include […]
