| BASIC RESULTS - Cont'd.{John DeLooze - Company Secretary} (3) Removing the undershield increases the speed to 2.3 M.P.H. (4) Fitting streamline body 110 M.P.H. (Assuming engine H.P.'s similar) PREDICTING SPEED OF PAULIN BENTLEY FROM DRAG. MEAN DECN. TIME 80 - 70 9.1 SECS. (1) 70 - 60 10.5 SECS. (2) Mean Velocity (1) = 75 M.P.H. = 110 (2) = 65 M.P.H. = 95.5 H.P. due to rolling (1) = 30 x 110 / 550 = 6 x 1.5 Rolling T.R. (2) = 30 x 95.5 / 550 = 5.2 x 1.5 30 lbs/Ton Total mean T.R. (1) 1.62 ft/sec = 1.62 / 32.2 x 3425 lbs T.R. (2) 1.4 ft/sec = 1.4 / 32.2 x 3425 lbs T.R. (1) = 172 lbs/ Total T.R. (2) = 150 lbs/Total T.R. Continued. | ||
