Angular Position given Radial Velocity for Lifting Flow over Circular Cylinder Solution

STEP 0: Pre-Calculation Summary
Formula Used
Polar Angle = arccos(Radial Velocity/((1-(Cylinder Radius/Radial Coordinate)^2)*Freestream Velocity))
θ = arccos(Vr/((1-(R/r)^2)*V))
This formula uses 2 Functions, 5 Variables
Functions Used
cos - Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle., cos(Angle)
arccos - Arccosine function, is the inverse function of the cosine function.It is the function that takes a ratio as an input and returns the angle whose cosine is equal to that ratio., arccos(Number)
Variables Used
Polar Angle - (Measured in Radian) - Polar Angle is the angular position of a point from a reference direction.
Radial Velocity - (Measured in Meter per Second) - Radial Velocity represents the speed of an object's motion along the radial direction.
Cylinder Radius - (Measured in Meter) - The Cylinder Radius is the radius of its circular cross section.
Radial Coordinate - (Measured in Meter) - Radial Coordinate represents the distance measured from a central point or axis.
Freestream Velocity - (Measured in Meter per Second) - The Freestream Velocity signifies the speed or velocity of a fluid flow far from any disturbances or obstacles.
STEP 1: Convert Input(s) to Base Unit
Radial Velocity: 3.9 Meter per Second --> 3.9 Meter per Second No Conversion Required
Cylinder Radius: 0.08 Meter --> 0.08 Meter No Conversion Required
Radial Coordinate: 0.27 Meter --> 0.27 Meter No Conversion Required
