1 nm = 1852 m g = 9.80665 m/s**2 rho (air density) = 1.225 kg/m**3 then the difference in level of the water columns in millimetres is given by h = 0.01654 V**2 where V is in knots. (I am using ** to indicate ¨raising to the power¨) For example at 160 kt we find 0.01654x160x160 = 423 mm cheers Ken _______________________________________________ Aus-soaring mailing list [email protected] To check or change subscription details, visit: http://lists.internode.on.net/mailman/listinfo/aus-soaring
