Absolute Velocity of Surges Solution

STEP 0: Pre-Calculation Summary

Formula Used

Absolute Velocity of Issuing Jet = sqrt([g]*Depth of Flow)-Mean velocity
v_abs = sqrt([g]*d_f)-v_m
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

Absolute Velocity of Issuing Jet - (Measured in Meter per Second) - Absolute Velocity of Issuing Jet is actual velocity of jet used in propeller.
Depth of Flow - (Measured in Meter) - Depth of Flow is the distance from the top or surface of the flow to the bottom of a channel or other waterway or Depth of Flow at the Vertical while measuring Sound Weights.
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.

STEP 1: Convert Input(s) to Base Unit

Depth of Flow: 3.3 Meter --> 3.3 Meter No Conversion Required
Mean velocity: 1.1 Meter per Second --> 1.1 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

v_abs = sqrt([g]*d_f)-v_m --> sqrt([g]*3.3)-1.1

Evaluating ... ...

v_abs = 4.58875601515832

STEP 3: Convert Result to Output's Unit

4.58875601515832 Meter per Second --> No Conversion Required

FINAL ANSWER

4.58875601515832 ≈ 4.588756 Meter per Second <-- Absolute Velocity of Issuing Jet
