  Centrifugal  \Cen*trif"u*gal\,  a.  [L.  centrum  center  +  fugere  to 
  flee.] 
  1.  Tending,  or  causing,  to  recede  from  the  center. 
 
  2.  (Bot.) 
  a  Expanding  first  at  the  summit,  and  later  at  the  base, 
  as  a  flower  cluster. 
  b  Having  the  radicle  turned  toward  the  sides  of  the

  {Centrifugal  force}  (Mech.),  a  force  whose  direction  is  from 
  a  center. 
 
  Note:  When  a  body  moves  in  a  circle  with  uniform  velocity,  a 
  force  must  act  on  the  body  to  keep  it  in  the  circle 
  without  change  of  velocity.  The  direction  of  this  force 
  is  towards  the  center  of  the  circle.  If  this  force  is 
  applied  by  means  of  a  string  to  the  body,  the  string 
  will  be  in  a  state  of  tension.  To  a  person  holding  the 
  other  end  of  the  string,  this  tension  will  appear  to  be 
  directed  toward  the  body  as  if  the  body  had  a  tendency 
  to  move  away  from  the  center  of  the  circle  which  it  is 
  describing.  Hence  this  latter  force  is  often  called 
  centrifugal  force.  The  force  which  really  acts  on  the 
  body  being  directed  towards  the  center  of  the  circle  is 
  called  centripetal  force,  and  in  some  popular  treatises 
  the  centripetal  and  centrifugal  forces  are  described  as 
  opposing  and  balancing  each  other  But  they  are  merely 
  the  different  aspects  of  the  same  stress.  --Clerk 
  Maxwell. 
 
  {Centrifugal  impression}  (Physiol.),  an  impression  (motor) 
  sent  from  a  nerve  center  outwards  to  a  muscle  or  muscles 
  by  which  motion  is  produced. 
 
  {Centrifugal  machine},  A  machine  for  expelling  water  or  other 
  fluids  from  moist  substances,  or  for  separating  liquids  of 
  different  densities  by  centrifugal  action  a  whirling 
  table. 
 
  {Centrifugal  pump},  a  machine  in  which  water  or  other  fluid 
  is  lifted  and  discharged  through  a  pipe  by  the  energy 
  imparted  by  a  wheel  or  blades  revolving  in  a  fixed  case. 
  Some  of  the  largest  and  most  powerful  pumps  are  of  this 
  kind

  adj  1:  tending  to  move  away  from  a  center;  "centrifugal  force" 
  [ant:  {centripetal}] 
  2:  tending  away  from  centralization,  as  of  authority;  "the 
  division  of  Europe  into  warring  blocs  produces
