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 […]
