Solving for average axial velocity of water flow.

## Inputs:

average axial velocity of water flow (L)
angle between acoustic path and the pipe's longitudinal axis (θ)
acoustic signal downstream travel time (td)
acoustic signal upstream travel time (tu)

## Conversions:

average axial velocity of water flow (L)
= 0
= 0

angle between acoustic path and the pipe's longitudinal axis (θ)
= 0
= 0
acoustic signal downstream travel time (td)
= 0
= 0
