Cazuela de Vaca (Beef and Pumpkin Stew) This hearty Chilean stew of beef, corn, and pumpkin is a one dish meal. The main ingredients are stewed in serving-sized pieces, so that each person receives a large piece surrounded by a broth with the other vegetables.
Quick Answer. A rotary vane vacuum pump works by using centrifugal force to turn blades against the circular surface of a cylinder whereby pockets of air are pushed from an inlet port to an outlet port as air pressure increases.
The typical home sump pump uses a centrifugal pump to move water. When the motor is on, it causes a screw- or fanlike device called an impeller to turn. Using centrifugal force, the spinning impeller forces water toward the sides of the pipe, creating a low-pressure area at its center.
