Coefficient of Discharge given Discharges Solution

STEP 0: Pre-Calculation Summary
Formula Used
Coefficient of Discharge = Actual Discharge/Theoretical Velocity
Cd = Qactual/Vtheoritical
This formula uses 3 Variables
Variables Used
Coefficient of Discharge - Coefficient of Discharge is ratio of Actual discharge to theoretical discharge.
Actual Discharge - (Measured in Cubic Meter per Second) - Actual discharge is given by the actual area and velocity.
Theoretical Velocity - (Measured in Meter per Second) - Theoretical Velocity describes the maximum speed an object falling from a given height would reach if there was no air resistance.
STEP 1: Convert Input(s) to Base Unit
Actual Discharge: 0.587 Cubic Meter per Second --> 0.587 Cubic Meter per Second No Conversion Required
Theoretical Velocity: 1.5 Meter per Second --> 1.5 Meter per Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Cd = Qactual/Vtheoritical --> 0.587/1.5
Evaluating ... ...
Cd = 0.391333333333333
STEP 3: Convert Result to Output's Unit
0.391333333333333 --> No Conversion Required
FINAL ANSWER
0.391333333333333 0.391333 <-- Coefficient of Discharge
