## How do you calculate lifting power?

The lift equation states that **lift L is equal to the lift coefficient Cl times the density r times half of the velocity V squared times the wing area A**. For given air conditions, shape, and inclination of the object, we have to determine a value for Cl to determine the lift.

## How much weight can a 3 HP motor lift?

Manufacturers have added excessive force auto shutoff and a nylon gears that fail when too much force is exerted. Actual figures are closer to 125 lbs for a 1/2 HP and **175 lbs for a** 3/4 HP.

## How much weight can a 12V DC motor lift?

Weight: **100 gm(Approx.)** RPM: 100 Operating Voltage: 12V DC Gearbox: Attached Plastic (spur)Gearbox Shaft diameter: 6mm Shaft Length: 21 mm Torque: 1.2 Kg-cm. No-load current = 60 mA(Max) Load current = 300 mA(Max).

## What is the efficiency formula?

Efficiency is often measured as the ratio of useful output to total input, which can be expressed with the mathematical formula **r=P/C**, where P is the amount of useful output (“product”) produced per the amount C (“cost”) of resources consumed.

## How much energy does it take to lift 1kg 1m?

Lifting Weights:

On earth it takes **about 10 Newton-meters (N-m)** of energy to raise a 1 kilogram mass to a height of 1 meter.

## How much force is needed to lift the 10Kg weight?

How much force is needed to lift the 10Kg weight? The correct answer is (B) **5 Kg**. In a double-pulley system, the force is equal to the weight divided by two. It will require a 5 Kg force to lift a 10Kg weight.

## How much weight can a 1 hp motor lift?

The constant 1 horsepower equals **550 foot-pounds per second**. In other words, 1 horsepower is the amount of work required to move a load of 550 pounds over 1 foot, in 1 second.

## How much weight can a 1/2 hp motor lift?

A 1/2 horsepower garage door opener can lift **approximately 300 pounds**, which is the average weight of a two-car steel door. A one-horsepower opener can easily lift approximately 400 pounds. The greater the horsepower, the faster the opener can lift the door, although some are designed to lift faster than others.

## How much weight can a 3/4 hp garage door opener lift?

How to know the garage door opener force fits the garage door weight?
