Uniform flow velocity for stream function at point in combined flow
Uniform Flow Velocity = (Stream function-(Strength of Source/(2*pi*Angle A)))/(Distance from end A*sin(Angle A))
Stream Function at Point in Combined Flow
Stream function = (Uniform Flow Velocity*Distance from end A*sin(Angle A))+((Strength of Source/(2*pi))*Angle A)
Location of stagnation point on x-axis
Distance of Stagnation Point = Distance from end A*sqrt((1+(Strength of Source/(pi*Distance from end A*Uniform Flow Velocity))))
Stream function at point
Stream function = -(Strength of Doublet/(2*pi))*(Length y/((Length x^2)+(Length y^2)))
Strength of doublet for stream function
Strength of Doublet = -(Stream function*2*pi*((Length x^2)+(Length y^2)))/Length y
Uniform flow velocity for Rankine half body
Uniform Flow Velocity = (Strength of Source/(2*Length y))*(1-(Angle A/pi))
Dimensions of Rankine half-body
Length y = (Strength of Source/(2*Uniform Flow Velocity))*(1-(Angle A/pi))
Strength of source for Rankine half body
Strength of Source = (Length y*2*Uniform Flow Velocity)/(1-(Angle A/pi))
Radius = sqrt(Strength of Doublet/(2*pi*Uniform Flow Velocity))
Distance of stagnation point S from source in flow past half body
Radial Distance = Strength of Source/(2*pi*Uniform Flow Velocity)
Stream function in sink flow for angle
Stream function = (Strength of Source/(2*pi))*(Angle A)

ur = q/(2*pi*r1)

The radial velocity of an object with respect to a given point is the rate of change of the distance between the object and the point. That is, the radial velocity is the component of the object's velocity that points in the direction of the radius connecting the point and the object.

## What is source flow?

Source flow is defined as the two-dimensional flow coming from a point called the source and moving out radially on a plane at a uniform rate.
