This calculator is used to find the approximate maximum speed of your brushless-powered R/C vehicle. The velocity/speed of an moving object can be determined by using the following formula: where v is the velocity/speed, D is the distance and t is the time (duration). See my Free Android Drag Racing Calculator App in the Google Play Store. If you want to get an idea of what kind of elapsed time your car will run at the drag strip. Schmitt) computes the maximum height, range, time to impact, and impact velocity of a ballistic projectile. The drag equation states that drag (D) is equal to a drag coefficient (Cd) times the density of the air (r) times half of the square of the velocity (V) times the wing area (A) . In this lab, the drag force will be explored between a fluid, air, and a solid shape. For mini bikes 35mph is the top speed when using a torque converter. For example 0 to 60 km/h in 10 seconds can be specified as a 60km/h speed change in 10 seconds, or a 6 km/h change in 1 second. In almost all cases the graph forms a U-shape, due to the two main components of drag. This item: Moroso - 89650 POWER-SPEED CALCULATOR $14. For airflow near and faster than the speed of sound, there is a large increase in the drag coefficient because of the formation of shock waves on the object. Moroso 62293 Jet Tool $18.

Front-wheel drive cars are different from rear-wheel drive cars, and all-wheel drive cars are different Vehicle Speed Calculator over Multiple Surfaces and then Impacts. The drag coefficient may further be a function of the Reynolds number. Your motor will have a limit to the number of amps it can handle. Note: This is a rough and quick estimate of engine horsepower. 60 foot. This calculator doesn’t take drag in to consideration. In general, the dependence on body shape, inclination, air viscosity, and compressibility is very complex. 333) × 5. Ships from and sold by Amazon. Even if you attempted to employ a drag coefficient for air resistance as the car’s velocity increases, headwinds and tailwinds further alter its potential top speed and gearing changes via up-shifts to taller gearing further increase the time required for the engine to increase its RPM to achieve its power-band therefore, the car’s top If you know your vehicle's weight and horsepower, this calculator can determine how you car will perform in a quarter mile "stretch".

This creates drag that must be overcome by the power of the rowers. MOR-89650. Car Stats Calculator. 65. When the two are equal, i. Most importantly, the maximum lift-to-drag ratio is independent of the weight of the aircraft, the area of the wing, or the wing loading. It also computes charts for Gear Ratio Slope, RPM Gear Drop and a Shift Point Chart. 0B. 5 A (v T - v P) 2. It doesn’t matter whether you want to calculate velocity with the distance covered, acceleration, and average velocity method; this velocity solver will help you in calculating velocity. ” [1] This can occur between two differing fluids or between a fluid and a solid. 825. 015 represents ordinary car tires on concrete (see Wikipedia for other sample values). Drag Racing. Elapsed time is the duration a vehicle takes to complete a run in a competition. Simply enter the four figures for your vehicle and see what you face horsepower-wise to meet your objectives. Cd: Coefficient of drag. Vehicle Speed Calculator over Multiple Surfaces and then Impacts. This does not tell the whole story, because in on water rowing, greater body weight submerges the boat deeper in the water. Crr: Coefficient of rolling resistance (rolling drag). This calculator is built on the core of the Table Tennis Ball Calculator and starts with base variables matching that calculator. If the drag force is smaller than the pulling force force, it will be decelerating. com Calculate the theoretical 1/8 Mile ET, 1/4 Mile ET, 1/4 Mile Top End Speed, and Ideal 1/4 Mile Gear Ratio for a given application based on the Vehicle Weight (in pounds), Vehicle Horsepower (at the flywheel), RPM through lights (finish line), and Tire Diameter (Height) in Inches. So you say you need to know the drag coefficient (CD) of your vehicle in order to perform acceleration, top speed, and other calculations, but you don't have your own wind tunnel or time for building scale models? Speed-Wiz can help! By performing coast-down time tests, you can get a very close estimate of your Air Flow Drag Coefficient Equations and Calculator. Parasitic Drag or Interference Drag - Incurred by the non-liftting parts of the aircraft such as the wheels, fuselage, tail fins, engines, handles and rivets. 92 Hg Air Flow Drag Coefficient Equations and Calculator. The results you obtain from this calculator are just guestimations, though. An 11% driveline loss is assumed for Wheel HP. We will use the drag force, or "wind resistance force" equation, which is . 5 * CdA * Air density * Speed^2. R ET is BEST possible ET for the speed, unless trap speed is skewed by a factor detrimental to acceleration (excessively loose converter, wrong gears, etc. ft. This calculator is used to calculate the speed of a vehicle traveling over one or more surface types and takes into account an impact with another vehicle or object. Enter the density of a fluid (1. Simply select the driven wheels for your car, enter the kerb weight (KG) and the flywheel horsepower (BHP). 2 Data Entry The active cells are the Green cells. This decrease in net force reduces acceleration. Practice Tree v2. Enter Shift at RPM, select gear to shift to and hit Shift and Trace to run up through the gears recording shift point RPM and km/h. Most of the drag on a car is aero dynamic drag rather than rolling resistance (from tires and weight). In many cases this results in the larger person scoring better on the erg. 0 Date Reviewed: 22/12/16 Page 5 of 14 2. Racing calculators for determining horsepower, ET, MPH, converter slip, engine displacement and more. The drag force equation used for the calculation on this page is (Blevins, 2003 and Munson et al.
