Does anyone know what drag coefficient you use for a ZP pilot chute (vented or non-vented) in the drag equation (http://en.wikipedia.org/wiki/Drag_equation)?

John Sherman at the Jump Shack might be a good person to ask.
About 20 years ago, jumpers would put a large vertical pole on the flat bed of their truck and measure the pilot chute drag versus speed using a bridle and spring scale.
