How do you convert pounds of thrust to horsepower?
How do you convert pounds of thrust to horsepower?
Thrust to Horsepower Calculator
- Formula. HP = T * V / 375.
- Thrust (pound force)
- Velocity (miles per hour)
How much horsepower is 70 pounds of thrust?
Pounds of Thrust to Horsepower Chart
| Pounds of Thrust (lbs) | Amps | Horsepower |
|---|---|---|
| 70 | 42 | 1.01 |
| 80 | 56 | 1.35 |
| 101 | 46 | 1.66 |
| 112 | 52 | 1.87 |
How many pounds of thrust equals one horsepower?
Depending on which math formulas and efficiency assumsions you want to accept, a single HP is some where between 75 and 110 pounds of thrust. For an average trolling motor, figure towards the high end of this scale.
How do you calculate thrust horsepower?
description. Thrust horsepower of jet engines and rockets is equal to the thrust in pounds force times the speed of the vehicle in miles per hour divided by 375 (which is equal to one horsepower measured in mile-pounds per hour).
How many pounds equal a horsepower?
Weight to power is one way to get a general idea of acceleration performance. For example, if I have a 3500 lb car with 215 horsepower, I simply divide 3500 by 215 to get a weight to power ratio of 16.28 lbs per horsepower. The same car with 250 hp would have a weight to power ratio of 14 lbs per horsepower.
Is thrust equal to torque?
The torque that is produced by the engine is converted to thrust by the combined effect of the gear ratio with our propeller. Physics teaches us that the Torque is proportional to the horsepower (Hp) and inversely proportional to the rotation speed (Rpm).
How much thrust does a 3 hp outboard have?
A 3 hp outboard will blow a 50 pound thrust electric motor out of the water – I have both and can make that statement. I can hold the boat with the 3 hp running so it isn’t pushing a tremendous amount. A 5 hp probably has somewhere near or over 200 pounds of thrust.
How many pounds of thrust do I need for my boat?
Boat weight is key when determining how much thrust you need. General rule of thumb: you need at least 2 lbs. of thrust for every 100 lbs. of fully-loaded boat weight (people and gear included).
How much horsepower does a 55 lb thrust trolling motor have?
Using this formula the popular Newport Vessels NV-Series 55lb Thrust Trolling Motor is rated as 624 watts at the highest forward speed and so 624/746 = 0.84 and would be roughly equivalent to a 0.84 horsepower motor.
What is pound thrust?
A “pound of thrust” is equal to a force able to accelerate 1 pound of material 32 feet per second per second (32 feet per second per second happens to be equivalent to the acceleration provided by gravity).
How do you measure pounds of thrust?
The thrust-to-weight ratio is calculated by dividing the thrust (in SI units – in newtons) by the weight (in newtons) of the engine or vehicle. Note that the thrust can also be measured in pound-force (lbf), provided the weight is measured in pounds (lb).
How do you calculate pounds of thrust?
Divide the converted horsepower by the velocity to calculate the thrust. For this example, 330,000 lb. ft/minute divided by 40 feet/minute equals 8,250 lbs. The thrust is 8,250 lbs.
How does thrust in pounds relate to horsepower?
Re: lbs thrust to english horsepower Power is force times velocity. One horsepower is 550 foot-pounds per second. So at 550 feet per second (375mph), each pound of thrust is one horsepower. At 825 feet per second (560mph), each pound of thrust is 1.5 horsepower.
How many pounds of thrust equal one horsepower?
The Oxford Dictionary defines horsepower as a unit of power equal to 550 foot-pounds per second. Because horsepower represents the total produced power of a system, however, it is not directly relatable to thrust.
How does horsepower compare to thrust?
In fact, the thrust and horsepower measures totally different things: The pounds of thrust is a static force measurement. It is a result of the power developed by the electric motor, the propeller shape, pitch and dimensions, and the speed in revolution per minute. Horsepower is a measurement of “work” being performed.
What is the conversion for lbs thrust to horsepower?
Pounds of Thrust to HP Conversion Chart So 1 hp trolling motor basically equals to 70 lbs of thrust, and about 0.6 horsepower is a 55 lb thrust trolling. More Thoughts About Horsepower vs Thrust Here are some common confusions or misunderstandings of the lb thrust to horsepower.
