However, we have based our knots calculator on the international nautical mile which is commonly used thoughout the world today. Time = 2 hours and 25 minutes is the solution. Theoretical displacement hull speed is calculated by the formula: velocity in knots = 1.35 x the square root of the waterline length in feet. Calculate the distance between the vehicles after 10 minutes given that both vehicles are travelling in the same direction. On the chart 17'-7" is about half way between 17 and 18 feet, so hull speed is 6.5 mph. Thus get shaft HP as a function of rpm, and so consumption. Hull Speed Formula. 20% 125 = 25 where 25 is 20% of 125. This is colour coded to give an immediate idea of the potential performance of that prop with the selected motor KV and battery voltage. This measure is a factor of the waterline obtained by calculating the hull's speed while sailing. Table 1. Use the CalcT button to figure the theoretical speed from the actual speed and slip. The formula for average speed, also called average velocity in physics and engineering, is: v = d / t. where v is the velocity, d is the distance, and t is the time, so you can read it as Speed = Distance / Time. The calculated propeller sizes are . A Train accelerates to a speed of 20 m/s over a distance of 150m.
