What is the difference between horsepower and kilowatts?
ANSWERHorsepower (hp) is a measurement unit that measures power in foot pounds per time (ft-lbs/t).Kilowatts (kW - 1000 watts) is a measurement unit that measures the work done when a force of one newton moves the point of its application a distance of one metre in the direction of the force.kW is the capacity to do work (like a standing horse)kWh is a measure of power - the amount of work done in one hour *(horsepower)*Horsepower is the rate at which a horse can do work in a given amount of time (distance x force/time):550 ft-lbs./sec or 33,000 ft-lbs/minute or 1,980,000 ft-lbs/hour.1 kW = 1.34 hp and 1 kW = 2,655,223 ft-lb/hour1.34 x 2,655,223 = (approx.) 1,980,000 ft-lbs/hour or 1 hp
How much work is done in lifting a 300-lb load of bricks to a height of 60 feet on a building under construction?
The work done in lifting the load of bricks can be calculated using the formula: work = force x distance. In this case, the force is the weight of the load (300 lbs) and the distance is the height it was lifted (60 feet). Therefore, the work done is 18,000 foot-pounds (300 lbs x 60 feet).
What weight of cargo could a barge carry if it was 100ft long x 25 ft wide x 10 ft high and it was lowered 4 ft into the water?
The weight of the barge plus cargo will equal the weight of the water it displaces. If the barge sinks to a depth of 4' then the volume of barge under water is 4 x 25 x 100 = 10,000 cf. This will also be the volume of water displaced. Water weighs 62.4 lbs per cf so 10,000 cf weighs 624000 lbs. This will be the cargo weight plus the weight of the barge. No way to separate the two weights, but the barge weight is probably a small portion of the total.
21 tons equals how many pounds?
That depends upon which ton you mean which depends upon where you are: * In UK where the ton is the long ton of 2240 lb, 12 tons = 12 x 2240 lb = 26880 lb * in USA where the ton is the short ton of 2000 lb, 12 tons = 12 x 2000 lb = 24000 lb
How many gallons in 8 ft x 8 ft x 3 ft container?
There are approximately 1,006 gallons of water in an 8 ft x 8 ft x 3 ft container.
How much work is accomplished when an 800-lb condensing unit is lifted to the top of a 40 ft buildin?
Well, your formula is w=fd, or work=force x distance, so 800x40= 32,000 J (jules)
How many Foot pounds per second are needed to raise 9000 lb a distance of 18 ft in 60 seconds?
The total work is (9000 x 18) = 162,000 foot-lbs.To get it done in 60 seconds requires power at the rate of (162,000 / 60) = 2,700 ft-lbs/sec.
How much 140 cubic foot concrete is in kg?
The density of concrete varies, but is about 150 lb/cu ft. mass = density x volume = 140 cu ft x 150 lb/cu ft = 21000 lb 1 lb ≈ 0.454 kg → 21000 lb ≈ 21000 x 0.454 kg ≈ 9525 kg (= 9.525 tonnes)
Storage unit that measures 14 ft x 15 ft x 14 ft?
2940 cubic feet
How much does a column of water weigh if the column's height is 15 miles and its diameter is 5 feet?
pi x (2.5 ft)2 x 15 mi x 5280 ft/mi x 62.4 lb/ft3 ÷ 2000 lb/ton ≈ 48,519 tons
What is the volume of a 10ft. X 6ft. X 22in. rectangle?
A "10 ft x 6 ft x 22 in" object is not a rectangle; a rectangle is a 2 dimensional shape whereas that is a three dimensional object - it is a cuboid.To calculate the volume of a "10 ft x 6 ft x 22 in" cuboid you need to work in one unit - either feet or inches:12 in = 1 ft⇒ 10 ft x 6 ft x 22 in = 10 ft x 6 ft x (22 ÷ 12) ft= 110 cu ftor:1 ft = 12 in⇒ 10 ft x 6 ft x 22 in = (10 x 12) in x (6 x 12) in x 22 in= 190080 cu in
What is the weight of one cubic foot block of wood if 6.25 inches of the wood weighs 9.5 pounds?
If 6.25/12 cu ft = 9.5 lb, then 1 cu ft = 12/6.25 x 9.5 lb = 18.24 lb
How many 40 lb bags of top soil would you need to cover the following areas. 6 ft x 4 ft and an 4 ft x 4 ft?
Half a ton at 3 inches deep.
How many inches in one sq yd?
This is Unit Conversion 1 square yard x 3 ft/yd x 3 ft/yd x 12 in/ft x 12 in/ft = 1296 square inches
How many cubic inches in 1 cubic unit?
It all depends upon what the unit is.For example:If the unit is centimetres, then:1 in = 2.54 cm ⇒ 1 cu in = 1 in x 1 in x 1 in= 2.54 cm x 2.54 cm x 2.54 cm= 16.387064 cu cm≈ 16.387 cu cmIf the unit is feet, then:1 in = 1/12 ft ⇒ 1 cu in = 1 in x 1 in x 1 in= 1/12 ft x 1/12 ft x 1/12 ft= 1/1728 cu ft≈ 0.000579 cu ft
How many is 5 inches equals in ft?
? ft= 5 in x 1 ft/12 in = 5/12 ft = 0.417 ft (The unit "inches" cancels out, leaving only the unit "feet" on the numerator/top of the fraction. Then, the numbers are divided to get the answer.)
