Horsepower to foot-pounds per second Note: The results you obtain from these calculators are just guestimations, though. Quarter Mile Calculator - Good Calculators One mechanic or hydraulic horsepower is equal to 745.699872 watts: 1 hp(I) = 745.699872 W. So the power conversion of watts to horsepower is given by: P (hp) = P (W) / 745.699872. Since 1 HP is equal to 746 W simply multiply the horsepower by 746 for this conversion. Since motors are not 100% efficient, the number of amps needed to achieve the power output is actually higher depending on the efficiency. This web site makes use of so called mechanical horsepower and uses one (1) Horsepower as equal to 745.699872 watts or equal to 550 foot-pounds per second. ET Equation: ET = 5.825 (WT / HP) 1/3 MPH Equation: MPH = 234 (HP / WT) 1/3. This result is usually between 1 Example: Dimensions of concrete block are: 3 meter * 2 meter * 1 meter. How to Calculate Horsepower Convert 10W to mechanic horsepower: P (hp) = 10W / 745.699872 = 0.01341 hp . flywheel horsepower. Does a horse have to be 3 to run in the Kentucky Derby? The power-to-weight ratio calculator uses the following formulas to calculate the power-to-weight ratios: PWR (hp/lb) = P (hp) / WT (lb) PWR (W/kg) = P (W) / WT (kg) Where: PWR= Power-to-weight ratio (horsepower per pound, watts per kilogram), P= Power (horsepower, watts), WT= Weight (pounds, kilograms).

If your running the 1/8 mile this calculator provides an accurate elapsed time and speed based on the horsepower and weight of the vehicle. Fill in any two of the three values to calculate the third. Divide the number of Watts by 746 to find out your horsepower rating. The answers below will be for at sea level and standard pressure/temperature. Trolling motors are rated in pounds of thrust. As a rule of thumb 72 to 75lb. of thrust roughly equals one horsepower or 746W of electrical power. A typical 12V motor that draws 60A consumes approximately 720W. ET-MPH-HP Calculator - Wallace Racing Enter speed or velocity - This is how fast the automobile is going at end of the 1/4 mile run or trap. Where: ET is the -mile elapsed time (seconds), MPH is the -mile trap speed of vehicle (mph), WT is the total weight of the vehicle and driver (lbs), HP is the peak engine horsepower (hp). Calculate HP, Weight or Speed. So 75 pounds of thrust of a For this method the horsepower equation is: HP = Weight x (the speed at which vehicle is moving (divided by) 234)3; If the weight is 50 and speed is 7 then by putting values in the above equation the HP will be 47.4 kilowatts. 1 Horsepower Enter speed or velocity - This is how fast the automobile is going at end of the 1/4 mile run or trap.

Torque to horsepower (hp) conversion formula. Various people came up with various equivalencies, but the modern agreed definition is that 1 ' horsepower is 746 joules per second or 746 watts. A metric horsepower (symbol often PS from the German abbreviation), approximately equal to 735.5 watts. description. So far, on the internet, I have read a) 22 lbs. This leaves me with 1 hp being able to vertically lift 12 pounds when accounting for the inefficiency of a propeller. Wallace Racing - ET/MPH/HP Calculator. Weight is as the car sits on the line: driver and gas in it. Unsprung weight vs. Sprung weight. & HP | DSMtuners.com For example, a 2,400 pound vehicle with a quarter-mile time of 11.65 seconds is making about 300 horsepower. In fact, the maximum output of a horse can be up to 15 horsepower, and the maximum output of a human is a bit more than a single horsepower. Watts to electrical horsepower. how much does it cost to enter a horse in the kentucky derby. Instead of calculating this handy stat on your own using the formula ET = constant*(weight/hp)^1/3, Calculator Pro takes the complications out of computing. Weight it is going to be around : (3 x 2 x 1) * 2400 = 14,400 Kg. Wiki User. Clearly this isn't right, so a more effective measure might be .35 pounds per amp. (no weather correction). What is a horsepower This calculator uses the following formulas: Calculate -mile ET from HP and weight: ET = ( (Weight HP) .333) 5.825. Horsepower Lets take Fred's example and say 25 pounds = a single HP. 1 horsepower is approximately equal to 6.91 amperes. flywheel horsepower (hp) weight (lb) elapsed time (seconds) speed (MPH) variable. Weight (lbs) Trap Speed (mph) Engine Motor Horsepower Estimate From Trap Speed Calculator HP is at the crank. In this case, removing 10.00 lbs of rotating weight from the driveshaft has the same effect as removing 26.6 lbs of dead weight from the car. Here is how to compare pounds of thrust to horsepower: 45 x 24 x 0.85 x 0.9/746 = 1.11 hp. Here is how you can get started on finding out the quarter-mile elapsed time of your car: At 1 pound of thrust per amp (not my assumsion, but Minnkota's, which I feel is less then half right) a 24 pounds (24 amps) of thrust motor times 12 volts, equals 288 watts. Also that for every 100lb removed = .1 less ET at the strip. The formula I've heard most is 10lbs equals 1 horsepower. Calculate -mile trap speed from HP and weight: MPH = ( (HP Weight) .333) 234. For example, if you weigh 180 lbs, and climb a 12-foot staircase in 4 seconds, that equals ( (180 * .454) * 9.81 * (12 * .3048)) / 4 = 733 watts. You get the weight of concrete block in Kgs. Also see our 1/8 mile calculator with incremental for additional run data. Calculate your Horsepower. Electrical horsepower to watts. Now the cool thing is, once your car weighs 2,000 lbs but still has 250 horsepower the percentage goes up. if someone could pull something that weighs 33,000 lbs one foot in one minute then they would have 1 horsepower). If your car weighs 2300 lbs, and has presently 215 hp, for example, then you have 10.75 lbs for each hp to lug about. Search: Boat Horsepower To Weight Ratio Calculator. Given a density of 2.72, we then get the product of 2.72 x 1,200 Calculate ET and MPH from HP and Weight. ET = 1353 / MPH. Calculation Instructions: Enter vehicle weight - This can be done by entering value or using the up and down arrows to step the number field. Well this is going to be equal to negative 18 times times 10 to the, nine plus negative three, same thing as nine minus three, which is six. Negative 18 times 10 to the sixth power.

Quarter Mile Calculator | Horsepower Speed Calculator Hp = 550 (f/p) Gravity = 32 (f/p) Hp / Gravity = 17.1875 So it seems 1 hp can hold 17 pounds in the air, but to incorporate propeller inefficiency, I just used 70% of that. b) 12 lbs. And for every 100lbs lost, your 1/4 mile time will drop a tenth. Torque is a rotational force generated by the electrical system, whereas, the horsepower is an imperial unit of power equal to 745.7 watts. Currently 4.54/5. Divide the number of Watts by 746 to find out your horsepower rating. How to Compare Weight Savings to Horsepower Gains Convert 10 hp to watts: P (W) = 745.699872 10hp = 7456.99872 W . Power to Weight Ratio (PWR) Calculator I assumed the driveshaft is the same diameter of a steel one, and that it is 5" diameter, that 3.73 gears are being used, and that all the weight was at the outside again. Therefore, it would seem that in this case removing 10.75 lbs from the overall weight OR adding 1 hp to the engine output would have roughly the same effect on performance. Study now. $ Refer to the example of one person exerting 40 pounds of force to pull an object 2 feet in 2 minutes. Horsepower (HP) is a non-metric measurement unit of power. [7] For example, if you weigh 180 lbs, and climb a 12-foot staircase in 4 seconds, that equals ( (180 * .454) * 9.81 * (12 * .3048)) / 4 = 733 watts.
