The 5 gallon tank measures 0.6685 cubic feet.  The compression ration is 15 (150 psi / 10 psi) so the tank holds 15 times as much air supply as its volume, or 0.6685 x 15 = 10.03 cubic feet. So, at 8000 cfm, you run out in 10.03 CF/8000cfm = .00125 minutes or 0.0752 seconds.

First off, just take the cube root (or use that x^y button on your calculator and raise the volume in question to the 0.3333333333 power). 1.8x10^6 cu ft would then be about 121 feet on a side.  Now, yourreal question is how big is 27,000 tons (I assume english units, not metric tons since you went to cubic feet).  That will depend on the density of the substance in question.  27,000 tons of water will take up more room than 27,000 tons of iron. The volume you gave gives a density of about 30lbs/cubic foot, which is about 1/2 the density of water.\n\nThis does sound like something hollow, like a boat, or maybe it is wood. That is a big block of wood. You gonna carve yourself an office building or something? A ten story cubic building is about that volume.

If it's an ellipse the area is pi*r1*r2, r1 and r2 being the semimajor and semiminor axes. This is 3.14*25*9 ~= 705 sq. ft. You'll have to estimate the average depth. If it's 4 feet you have 4*705 ~= 2820 cu ft. There are ~7.5 gallons in a cu ft, so that's 7.5*2820 ~= 21200 gallons.

I am a HVAC trainer in the USA, and as such I have to explain how to calculate what amounts of energy it takes to do a certain heating jobs.  Looking at your question, I am of the impression that you are asking how much energy it takes to bring the temperature of 100 gallons of water from 74deg F to 90deg F.  I will explain  how to do this calculation, plus ask and answer a question that I feel might be more appropriate to an application. \n\nMost HVAC technicians define a BTU as the amount of heat energy it takes to raise one pound of water one degree Fahrenheit.  Tables will state that there are approximately 8.34 pounds of water in one gallon of water.  Taking this information, we can calculate that there are 834 pounds of water in 100 gallons of water (100 * 8.34 = 834).   So, if we raised 100 gallons of water 1deg F, we will have put 834 BTU’s into that water.  The temperature difference you talk about is equal to the difference between 74deg and 90deg which is 16deg F (90 – 74 = 16).  If one degree requires 834 BTU’s, then 16 degrees will require 16 times that amount, or 13,344 BTU’s (834 * 16 = 13,344).\n\nNow for the real issue, if you have a flow of water entering the slab at 90deg F, and it comes out of the slab at 76deg F, and if the flow rate is …… lets say 8 gallons per minute, than how much energy is the water putting into the slab?  To answer this, we use the same concept as above except we figure the flow rate in pounds per hour and multiply that times the temperature difference.  The process goes like this: (8 gallons per minute) * (8.34 pounds per gallon) * (60 minutes per hour) = 4003.2 pounds per hour.  Now multiply the pounds per hour flow rate times the temperature difference, and we get the energy going into the slab (4003.2 * 16 = 64051.2 BTU’s per hour).  So, the heat pump would have to have a capacity of a little over 5 tons (1 ton is 12,000 BTU per hour) to meet that load. \n\nNow, the energy one puts into a slab should be based on the heat loss of the structure.  It might be that you only have to put 18,000 BTU’s into the slab to offset the heat loss.  The flow rate and temperature difference can be adjusted based on the heat loss.

I am assume stand temperature and pressures at the surface of the earth.\n\nThe volume of the liquid is: \n1 inch x 1 acre \n= 1 in. x 43560 sq. ft.\n= 1 in. x 208.71 ft x 208.71 ft (assume square acre)\n= 1 in. x 2504.52 in x 2504.52 in\n= 6272620.4 cubic inches \n= 27154.2 Gallons (assumung US Gallon)

One cubic feet of water is 7.48 gallons.\nFind the volume of water in your swimming pool.\nSuppose it is V cubic feet.\n(If your pool has the same depth d feet every where, then \nV = (10)(15)(d) = 150 d)\nThen the number of gallons of water is V/7.48.\n\n(If the depth is not the same every where, you can make an estimate of the number of gallons, by taking d = average depth)

Volume of Earth's Oceans = 3.28*10^8 mi^3\n\nconvert cubic miles to gallons:\n1 mi^3 = 5280^3 ft^3\n1 ft^3 = 7.48 US liquid gallons\n\nSo, volume = 3.28*10^8 * 5280^3 * 7.48 = 3.61*10^20\n\nAssume bucket size is 5 gallons (divide answer by 5):\n\n7.22*10^19 buckets are needed to fill all of Earth's oceans.\n\nThat's 72,200,000,000,000,000,000 5-gallon buckets, or 72.2 quintillion.

to convert from cubic feet to yds^3 you need the following\n\na cubic foot is 1ftx1ftx1ft\na cubic yard is 3ftx3ftx3ft = 27 cubic feet\nso 1 cubic yard is equal to 27 cubic feet\n\n6000/27 = 222.22, if  you need this to purchase dirt or something you have to round up, purchase 223 cubic yards

2" = 1/6 ft, so 60x20x(1/6) or (60x20)/6 will tell you how many cubic feet of sand you need.  However, these are both expressions.  To make an equation, you would write something like: \nV=60 ft x 20 ft x 1/6 ft \nwhere V is the volume of sand needed.\n\nIt works out to 200 cubic feet, by the way :)\n\nThe two previous answers are basically right except that volume can be expressed in neither square feet nor yards.  These are measures of area and distances, respectively.\n\nnotsomuch77 is right that you can convert from feet to yards by multiplying by 1/3.  However, to convert from _cubic_ feet to _cubic_ yards, you have to muliply by (1/3)^3, which is 1/27.  Basically, you have to muliply each length by 1/3, and when you do it three times it's the same as muliplying the whole thing by 1/27.

36 quarts = 9 gallons\n\nso we have 18 gallons, 15 gallons, and 9 gallons\n\nIf we fill the 18 gallons, then pour it into the 15 gallon container, this will leave 3 in the 18, and 15 in the 15.\n\nWe now pour from the 15 into the 9 to give us:\n\n3 in the 18\n6 in the 15\n9 in the 9\n\nNow just empty the 9 back into the 18 and it will have 12 gallons!\n\n:) Hope this helps!

This is pretty straightforward.\nFirst you have to write the formula fo rthe cost of the tank as a function of, say, its radius, r:\n\nThe volume of the cylinder is 100 cubic feet.\nIt is also pi*r^2 times the height, h\n\nso let's solve for h\n100=pi*r^2*h\nh = 100/(pi*r^2)\n\nnext, the cost:\nthe rectangle cost is 2.40*(h*2*pi*r),\nor 2.4*100/(pi*r^2)*2*pi*r\nor, simplifying, 480/r\nThe cost of the base and top are:\n1.50*2 pieces * pi*r^2\n\nSo the total cost is\n480/r+3*pi*r^2\n\nNow you need to differentiate this and find the roots, and make sure they are minima, not maxima!

You can convert it all to inches then divide by 1728 cubic inches/cubit foot to get.\n\n[(22x12)x(110x12)x3]/1728\n(264x1320x3)/1728\n1045440/1728=605 cubic feet\n\nOr you can convert the 3" to what that is in feet by dividing 3 by 12 to get 0.25'\n\n22x110x0.25=605 cubic feet

to figure out cubic meters, you multiply length times width times height.  so, 82746 in x 4 in x 2 in = 659,808 inches cubed\n\nthen you convert cubic inches into cubic feet by multiplying by 0 . 0005787, and then to cubic meters by multiplying by 0 . 0283168 \n\n(the other way to do this would be to convert the length measurements from feet into meters and then to multiply the new length width and height values together.  to convert from feet to meters, multipy by .3048)

Unfortunately, you did not.\n\nYou have to make sure that all your units are correct.  You mixed feet, inches and yards.\n\n20 ft x 15 ft x 6 in \n\n6 inches = .5 ft.\n\nSo, you get: 20 ft x 15 ft x .5 ft = 150 ft^3\n\n150 cubic feet = 50 cubic yards.\n\nRegards,\n\nMysstere

You cannot convert gallons into pounds per cubic foot because gallons are a volume and pounds per cubic feet is a density.\n\nWater weighs 8.33 pounds per gallon.  \nSo 425 gallons will weigh 3540 pounds.  \n\nThere are 7.48 gallons in a cubic foot.  So 425 gallons is about 56.8 cubic feet.
