Question $1$

What are the rules to draw a flow net? Check all that apply.

Flow lines never cross

Flow lines and equipotential lines are perpendicular

Each stream tube carries unequal flow

Each stream tube carries the same flow

Flow lines are perpendicular to no flow boundaries

Draw to scale

Flow lines and equipotential lines are parallel

Aspect ratio of shapes formed by intersecting stream and

equipotential lines must be different

Flow lines sometimes cross

Aspect ratio of shapes formed by intersecting stream and

equipotential lines must be constant

Flow lines are parallel to no flow boundaries
