";s:4:"text";s:14674:"For AC power supply, watts are equal to the power factor times amps times volts. To those not prone to maniacal laughter, 15 mph (25 km/h) is enough. Usain Bolt's maximum power output while sprinting was about 2.6 kilowatts. Depends on the amp hour rating. Cars motors are often rated in the rather old fashioned unit of horsepower. 15 MPH = 90 Watts (+14) Note how it takes double the watts to go 15 MPH than it does to go 11 MPH! I just read somewhere "It takes 100 watts to do 15 mph on level ground". AND you get to see the answer in 7 other different units !! Watts are then calculated as (2.80/0.25 ^ 3) or (2.80/0.015625), which equals 179.2. We assume you are converting between watt and kilocalorie/hour [I.T.]. watts w = 115.007 + (-15.8397 × s) + (1.15006 × s × s) Could you place a rough wattage range on that scenario? This is the equivalent of a 0.73% grade. 15 Watt in Lumens > find 15 watt replacement. What is 15 kilowatts in watts? The rating is somewhat like a car's horsepower figure. Looking for the number of lumens of a 15 Watt LED, incandescent, halogen or CFL bulb? The answer is 746.043. no headwind. However just for the hell of it I'll pretend this thread has a sane future. Cool down: 10 min (Easy spin followed by stretching) Easy endurance ride. Interesting - These charts seem to show zero wind conditions. Log in or register to join the conversation. At least most car buyers have already owned a car, so they have a rough ide… So watt-hours is equal to milliamp-hours times volts divided by 1000: Sprinters generate incredible amounts of power in the final 15-second dash for the line. METs Calories per 60 mins* Stationary cycling, 50 watts 3.0 215 Bicycling, leisurely 3.5 250 Stationary cycling, 100 watts 5.5 395 Bicycling, 12-13 mph 8.0 575 Bicycling, 14-15 mph 10.0 715 Bicycling, 16-19 mph 12.0 860 Bicycling, 20+ mph 16.0 1145 *Approximation based on 150 lb. 4 min recover. Will you be replying to any current threads too? but it is 10% of a bigger number, so the power needed is still more, if you ease off the power you will slow down! You missed the point. Yet, many … Besides rated wattage, wind generator manufactures also normally provide a so-called Power Curve (also known as a Performance Graph or Power Output Graph), that plots the output in watts or kilowatts as a function of instantaneous wind speed. I wonder if anybody has any idea how many watts you push at various speeds?? How many watt in 1 HP? A combined human and e-motor power of 150 watts is enough to make bicycle technology work and work well to meet much of our transportation needs. 1 min at 130-140% watts of your FTP. Ready, Set, Bike! what did you put in for the other variables (rider weight, bike weight etc). Watts are like miles-per-hour. watts … On firm, flat ground, a 70 kg (150 lb) person requires about 60 watts to walk at 5 km/h (3.1 mph). There are many different standards and types of horsepower. FIRST CHOOSE WHAT YOU ARE SOLVING FOR In this case we are solving for ENERGY, so click on that button. Estimate your Power from Speed. The calculators on this page calculate power from your speed and other parameters. Manc33 becomes interested in power numbers. E (Wh) = Q (mAh) × V (V) / 1000. How long is a piece of string? Click the CALCULATE button and this equals 61.149 miles per hour. We assume you are converting between watt and horsepower [water]. Watts increase with the square of the speed. Let me put it another way. I need a chart with all other variables factored in except it taking. 20 lb. The number of \"horses under the hood\" doesn't indicate the fuel efficiency or top speed without vehicle weight, driving conditions, and other stats. If in zero wind you are riding at 16mph with a power of 100 watts, then you ride into a headwind of 10mph but still maintain 100 watts by how much will that headwind reduce your speed? The aero drag force acting against you increases with your speed squared, i.e. bike. Power Current Voltage; 5 Watts: 0.4167 Amps: 12 Volts: 10 Watts: 0.8333 Amps: 12 Volts: 15 Watts: 1.25 Amps: 12 Volts http://www.gribble.org/cycling/power_v_speed.html, https://kurtkinetic.com/technical-infor ... ower-tech/, viewtopic.php?f=40044&t=13020685&p=19496365#p19496365, viewtopic.php?f=40044&t=13020702&p=19589281#p19589281, http://www.slidingseat.net/cycling/cycling.html. Note that rounding errors may occur, so always check the results. Holding 20MPH. On the home page. You can view more details on each measurement unit: watt or HP The SI derived unit for power is the watt. ... spin 15 mph around the same 20-mile loop three times a week expecting to make measurable fitness gains. Speed is defined as the rate at which someone or something moves or operates. For example: a 2:05/500m split = 125 seconds/500 meters or a 0.25 pace. 1 watt is equal to 0.85984522785899 kcal/hr. flat course. But that doesn't account for the loss of watts from a poorly indexed front mech and rubbing quick links. I'm confused by the unusually reasonable and bike-related nature of your query. What is her kinetic energy? Easily convert speed to watts using this online speed to watts conversion calculator, Consider that a bike is moving at a speed of 60km/hr. 18 mph: 26 mph: Average Bike Speed up an 5% hill: 9.5 mph: 15 mph: Average Bike Speed up an 8% hill: 7 mph: 12 mph: Fastest Downhill Bike Speeds: 47 – 57 mph: 69 – 81 mph: Average sustainable watts for 1 hour (FTP) 200 watts: 415 watts: 5 second Sprint: 33mph/700 watts: 40mph/1250 watts: Tour De France Average Speed: N/A: 25mph (average of the 3 weeks) 300 watt mid-drive motor…this is the most efficient bike on this list, meaning it will get you further per watt hour (we estimate 15 watt hours per mile). Firstly, rewrite the initial watts to amps formula into the amps to watts equation: P = 3 * V * PH * I, As long as all of the values have desired units, simply input them into the formula: P = 3 * 100 V * 0.9 * 15 A = 4050 W, The outcome can be expressed as: "15 amps to watts, for the VLN equal to 100 volts is 4050 W."
