What are the customary measurements of weight?
The usual measurement of weight is Metric, in Grams. You can also use U.S. measurements like Pounds and ounces. Metric system- Gram and Kilogram U.S.- Pounds, ounces, Tons
How does pulley make work easier?
A simple example is to imagine you're sitting on a swing attached to a rope and the rope goes up over a pully attached to the ceiling and back down. You could pull down on the other end of the rope to pull yourself up. It turns out the force you pull down with is only half of your weight, and it is actually pretty easy! My first year physics prof did this demo and pulled himself up 30ft to the ceiling in a large classroom. Why is it easy? If you look at the forces on the pully in isolation, the force pulling up on it must be equal to your weight (call this force W). There are two downward forces from the two ends of the rope hanging down which must balance the upward force. When you're not accelerating the forces on the ends of the rope are equal. Let the rope forces equal R. You get the following equaltion: W = 2R R = W/2
How much water does a 30ft round pool with 52 inch deep walls hold?
At 7.48 gallons per cubic foot that is 3.14x30x30/4x52 x7.48 /12 = 22,900 gallons
How many gallons of water are in a 30ft by 10ft rectangle pool?
It depends how deep it is.
What is the possiblility of pool failure in a 30ft round pool that is off level by 2 inches?
fill it and find out ;)
How many cm are in 30ft and 6inch?
There are 927.36 centimeters in 30 feet and 6 inches.
How many gallons of water in a 30ft round 54in wall?
If you filled the pool all the way to the top (54"), it would be holding around 11,708 gallons of water. If you filled to a depth of four feet (48") the volume would be about 10,408 gallons. As a side note, 11,708 gallons of water weighs about 49 tons.
How many gallons of water in a tank that is 100 feet x 30 feet x 20 feet?
There are 7.48 gallons in 1 cubic foot.Volume of tank = 100ft x 30ft x 20ft = 60000 ft3.60000ft3 x 7.48gal/ft3 = 448800gal
What is the height for the mens high jump in 2008?
30ft to 42ft 30ft to 42ft 30ft to 42ft 30ft to 42ft
How many gallons does a 30ft x 4ft pool hold?
volume= LWH surface area: A= 2HW+2LW+2LH for rectangular solid you need to add the width i think with your numbers it is almost 900 gallons
What is the average size of a park bathroom?
30ft by 30ft
How many gallons is a 30ft round 5 ft deep pool?
To determine the amount of water in an oval pool, calculate the area of the oval (elipse) and multiply that by the depth, then take that volume and plug it into a conversion factor. There is a "rule of thumb" for finding the area of an oval. It makes for a good approximation and allows us to avoid the calculus. It's l(length) x w (width) x 0.8 which in this case is 30 x 17 x 0.8 = 408 ft2 for the area. Multiply that by the depth, 5.5 ft, and you've got 2244 ft3 for a volume. Water has about 7.48 gallons per cubic foot, so your pool will hold about 16,785 gallons of water when filled to the brim. Sloping sides will strip something off that figure, obviously.
How much head pressure lossin a 30 foot rise?
30ft rise = 13 psi (pressure is 13 psi higher at bottom of a 30ft column that at the top). Water Pressure = .433 psi per ft for a column of water at 62 degrees F.
