Velocity of Flow given Depth of flow Solution

STEP 0: Pre-Calculation Summary

Formula Used

Mean velocity = sqrt([g]*Depth of Point 1)-Absolute Velocity of Issuing Jet
v_m = sqrt([g]*h ₁)-v_abs
This formula uses 1 Constants, 1 Functions, 3 Variables

Constants Used

[g] - Gravitational acceleration on Earth Value Taken As 9.80665

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Mean velocity - (Measured in Meter per Second) - Mean velocity of a fluid in a pipe or channel normally means the flow rate divided by the cross-sectional area of the flow.
Depth of Point 1 - (Measured in Meter) - Depth of Point 1 is the depth of point below the free surface in a static mass of liquid.
Absolute Velocity of Issuing Jet - (Measured in Meter per Second) - Absolute Velocity of Issuing Jet is actual velocity of jet used in propeller.

STEP 1: Convert Input(s) to Base Unit

Depth of Point 1: 10 Meter --> 10 Meter No Conversion Required
Absolute Velocity of Issuing Jet: 5.002 Meter per Second --> 5.002 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

v_m = sqrt([g]*h ₁)-v_abs --> sqrt([g]*10)-5.002

Evaluating ... ...

v_m = 4.90085312422637

STEP 3: Convert Result to Output's Unit

4.90085312422637 Meter per Second --> No Conversion Required

FINAL ANSWER

4.90085312422637 ≈ 4.900853 Meter per Second <-- Mean velocity
