6.3 A manufacturer's bulletin shows a graph of ie percent oxygen transfer in tap water at a 14ft ubmergence depth. For 7scim, the graph gives a ansfer efficiency of 18%. Pertinent data are: = 0,=1.0, operating D=0.0mg/, operating imperature =20C, and operating pressure = 4.7 psia (sea level). Determine, using USCS units, le constant C in the following performance quation: N=CGa0.9D0.67(CmCL)1.02T20a
