Fair Isaac Corp., or FICO, a company that produces one of the leading credit scores lenders use, offers two scenarios on its website that show how credit missteps (including bankruptcy) can affect scores. In these two scenarios, a bankruptcy filing can lower a credit score by as much as 240 points.
An impeller (also written as impellor or impellar) is a rotor used to increase (or decrease in case of turbines) the pressure and flow of a fluid.
Impellers (and jet-pumps) work on the principal of positive and negative pressure, or the push/pull concept. As a blade rotates, it pushes water back (and outwards due to centrifugal force). At the same time, water must rush in to fill the space left behind the blade.
