## Velocity Approach (Va) Solution

STEP 0: Pre-Calculation Summary
Formula Used
velocity = Discharge/(Width of the Channel*Depth of Flow )
v = Q/(w*d)
This formula uses 3 Variables
Variables Used
Discharge - Discharge is the rate of flow of a liquid (Measured in Meter³ per Second)
Width of the Channel - Width of the Channel is the dimension of the channel of MOSFET (Measured in Micrometer)
Depth of Flow - Depth of Flow of the discharge in the electro-magnetic method of stream flow measurements. (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit
Discharge: 1 Meter³ per Second --> 1 Meter³ per Second No Conversion Required
