How accurate are the radar control plates (C-band) in a quarter-mile strip?
Yesterday, we had a great day on the track local, where we test our cars and my bike down the quarter mile times. Since the system is connected to a laptop, it automatically connects the trap speed and the weight the vehicles, and power is how each participant was calculated completed. I have three running on my Cannondale and I are approximate PS as follows: 1 Run (best race) PS = 0.221 (weight = 129 pounds, speed = 28 kilometers per hour, elapsed time = 48.68 seconds) = 0.198 seconds run PS (weight = 129 pounds, speed = 26 km / h), third run = 0.177 PS (weight = 129 pounds, speed = 25 mph) Are the above numbers? PS: Yin was a time of 14.24 up to 96 km / h in the Volvo C30. Note: The tape is an old airfield, and a hand-held radar was used to accelerate to measure.
Kate hi I doubt the Power calculations are correct. His top speed trap should a rough overview of the average performance during the race. (Probably a little lower.) For a driver (the size) to around 28 miles an hour should be about 0.5 hp (conservative. take) I suspect that your computer uses the parameters of the cars to the calculations to be done. The most obvious difference would wind drag coefficient (cw). A typical car would typically 0.26 -0.4, 0.9 A rider. En.wikipedia.org http: / / / Wiki / Drag_coefficient basic formula for a flat, no wind. Power (W) = (1 / 2 * CD * A * ρ * V2 * CRR + W) = 0.9 V Cd Many motorcycles have a lower Cd much it. Once a rider is added is not very aerodynamic, the number of wind the Middle East. A = cross-sectional area of the cross (the average is is about 0.4 meters SQR.) Petite For a woman of about 0.34 M2 = ρ air density. I usually go with 1.22 kg / cubic meter, but this varies depending on temperature and air pressure, etc. V = velocity in meters / second. (28 mph = 12.5 m / s) = CRR rolling resistance coefficient (0.004 to 0.006 road bike on a flat and hard.) W = weight in kg likely get a more accurate value for power, when a car towed. Beware of a fragment of the band, with fast bike can damage the structure. The note, most JP Pro cyclists can maintain over 1000 watts peak and 400 watts (0.54 hp) for 30 minutes http://www.getoutdoors.com/goblog/index.php?/archives + / 1267-Power-Kick-Floyd Landis-ass-iBike Power Meter.html
