SUMMARY

The relationship between flow area, flow rate, and velocity is defined by the equation flow = area * velocity. In this context, flow is synonymous with flux, and the units for these measurements are critical. The correct units are: area in square meters (m²), flow rate in liters per second (L/s), and velocity in meters per second (m/s). Understanding these units is essential for accurately calculating fluid dynamics in various applications, particularly in physics and engineering.

PREREQUISITES
  • Basic understanding of fluid dynamics
  • Familiarity with units of measurement in physics

area = flow/velocity
Is this correct? Also can anyone tell me what the units should be. Is it m^2, L/s and m/s?

It will really depend on what flow you are talking about. In physics, flow is synonymous with flux. If you are talking about a water flow you would want flow = area*velocity.

velocity of has units of Length/time
area has units of Length^2
so flow must be Length^3/time

Eeh, mindscrape:
Please make that / into a *
 
thanks - I just got a little confused - I thought I had it wrong for a minute there.
 
Err, whoops, I did mean to say times but disconnect between what I meant to say and what I was looking at. My bad.
