Prototype
	Poor 1 pts	Fair 2.5 pts	Good 4 pts	Excellent 5 pts
Esthetics	Poor Equipment is not aesthetically nor geometrycally pleasant	Fair Equipment is aesthetically pleasant but geometrycally challenged	Good Equipment is logical geometrically	Excellent Equipment is logical geometrically, and pleasant aesthetically
Operation	Poor Equipment did not work	Fair Equipment worked with a great deal of effort on the part of the students	Good Equipment worked only with help from the students, but intervention was minimal	Excellent Equipment worked as by design
Capacity restriction	Poor Equipment does not meet the capacity	Fair Equipment almost reaches capacity but not quite, or is largely oversized	Good equipment meets capacity	Excellent Equipment meets capacity and has considerations for a little extra capacity
Flow rate	Poor it was not achieved, average and stardard deviation very large	Fair It was achieved in a few of the trials, average not achieved and standard deviation was low, implying uniform flow out of specification	Good it was achieved in most of the trials, average was met but standard deviation was high, implying nonuniform flow with errors	Excellent flow rate was achieved, average was met, and standard deviation was low.
Effort	Poor Equipment looks like a last minute effort	Fair Equipment was designed with little creativity of effort	Good Equipment design was thoughtfull	Excellent Equipment design was well planned and excecuted
