Discharge given Flow Area of Throat Solution

STEP 0: Pre-Calculation Summary

Formula Used

Environmental Discharge = Flow area of throat*Critical Velocity
Q_e = F_area*V_c
This formula uses 3 Variables

Variables Used

Environmental Discharge - (Measured in Cubic Meter per Second) - Environmental Discharge is the rate of flow of a liquid.
Flow area of throat - (Measured in Square Meter) - Flow area of throat is the area of throat through which flow is occuring.
Critical Velocity - (Measured in Meter per Second) - The Critical velocity is the greatest velocity with which a fluid can flow through a given conduit without becoming turbulent.

STEP 1: Convert Input(s) to Base Unit

Flow area of throat: 10 Square Meter --> 10 Square Meter No Conversion Required
Critical Velocity: 15 Meter per Second --> 15 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_e = F_area*V_c --> 10*15

Evaluating ... ...

Q_e = 150

STEP 3: Convert Result to Output's Unit

150 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

150 Cubic Meter per Second <-- Environmental Discharge

(Calculation completed in 00.004 seconds)
