What does a wind tunnel measure?

What does a wind tunnel measure? In wind engineering, wind tunnel tests are used to measure the velocity around, and forces or pressures upon structures. What does pressure coefficient mean? The pressure coefficient is a dimensionless number which describes the relative pressures throughout a flow field in fluid dynamics. The pressure coefficient is used in […]

Is quicksort recursive?

Is quicksort recursive? Overview of quicksort. Like merge sort, quicksort uses divide-and-conquer, and so it’s a recursive algorithm. The way that quicksort uses divide-and-conquer is a little different from how merge sort does. In merge sort, the divide step does hardly anything, and all the real work happens in the combine step. What is recursive […]

What is the fluid power industry?

What is the fluid power industry? Fluid power is the use of fluids under pressure to generate, control, and transmit power. Compressed-air and water-pressure systems were once used to transmit power from a central source to industrial users over extended geographic areas; fluid power systems today are usually within a single building or mobile machine. […]

How do centrifuges separate substances?

How do centrifuges separate substances? Centrifugation separates the components of heterogeneous mixtures. These include liquids in liquids, solids in liquids, and solids and liquids in gases. Centrifugation uses centrifugal force to move dense components to the outside of the container. This causes the solid to settle more rapidly and completely. What is centrifugation used to […]
