What is the mean velocity?

mean velocity. The time average of the velocity of a fluid at a fixed point, over a somewhat arbitrary time interval T counted from some fixed time t0. For example, the mean velocity of the u component is. The time average of any other quantity can be defined in this manner.

c u c l 2 + 2 n a n o 3 → c u ( n o 3 ) 2 + 2 n a c l

  long weird answer but i hope this works
