Consider the drag force $($Fo$)$ on an object with a characteristic length of $($I$),$ moving slowly at velocity $($v$)$through air. The drag force also depends on the $($M$,$ p$).$Find a suitable set of Pi terms$\mathrm{.}6$ Steps to Obtain Pi Terms:$1.$ List all parameters involved $($n$)2.$ Select a set of primary dimensions $($m$)13.$ List all of the parameters in terms of the primary dimensions$4.$ Select from the list in step $1$ parameters which collectively contain all of the primar Combined m parameters must contain all primary dimensions Each parameter must be dimensionally independent$15.$ Select one additional parameter and use m$+1$ parameters to form pi terms$6.$ Repeat step $5$ n$-$m$-1$ times or use dimensionless numbers
