Head given Discharge through Notch which is to be Calibrated Solution

STEP 0: Pre-Calculation Summary

Formula Used

Height of Water above Crest of Weir = (Francis Discharge with Suppressed End/Constant of Flow)^(1/Number of End Contraction)
S_w = (Q_Fr'/k_Flow)^(1/n)
This formula uses 4 Variables

Variables Used

Height of Water above Crest of Weir - (Measured in Meter) - Height of Water above Crest of Weir is defined as the water surface height above crest.
Francis Discharge with Suppressed End - (Measured in Cubic Meter per Second) - Francis Discharge with Suppressed End is discharge of flow without the end contraction.
Constant of Flow - Constant of Flow is calculated from 2/3 * Cd *L*Sqrt(2g).
Number of End Contraction - Number of End Contraction 1 can be described as the end contractions acting on a channel.

STEP 1: Convert Input(s) to Base Unit

Francis Discharge with Suppressed End: 28 Cubic Meter per Second --> 28 Cubic Meter per Second No Conversion Required
Constant of Flow: 1.84 --> No Conversion Required
Number of End Contraction: 4 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S_w = (Q_Fr'/k_Flow)^(1/n) --> (28/1.84)^(1/4)

Evaluating ... ...

S_w = 1.9750816408512

STEP 3: Convert Result to Output's Unit

1.9750816408512 Meter --> No Conversion Required

FINAL ANSWER

1.9750816408512 ≈ 1.975082 Meter <-- Height of Water above Crest of Weir

(Calculation completed in 00.004 seconds)
