To calculate the BTUs required to heat 120 gallons of water to 210°F, first determine the temperature rise needed. Assuming the initial water temperature is around 60°F, you would need to raise it 150°F (210°F - 60°F). The BTU calculation is:
[ \text{BTUs} = \text{gallons} \times \text{temperature rise} \times 8.34 ]
So,
[ \text{BTUs} = 120 \text{ gallons} \times 150°F \times 8.34 \approx 1,500,600 \text{ BTUs}. ]
To heat this in 2 hours, you would need about 750,300 BTUs per hour.
If the temperature dropped 2 degrees Fahrenheit every hour for 6 hours, the temperature would change 12 degrees. You multiply 2x6 to get the answer of 12.
You would mix 1 part something with 99 parts something else, so if you were preparing a 1% solution of salt in water, you would put if you wanted to make 6.25 gallons of this, you would have 1 cup of salt and 99 cups of water.
It would be less than half a gallon. Pounds is a unit of mass/weight. Gallons is a liquid measure. They do not convert cleanly. The density of the liquid being measured can make a big difference. If the liquid is water, there is 8 pounds to a gallon.
4 degrees would be 4/360*100 or 1.11%.
To determine the volume of water that fills a tank with dimensions 24 inches long, 12.5 inches wide, and 12.5 inches high, you can use the formula for volume: length × width × height. This gives you a volume of 24 × 12.5 × 12.5 = 3,750 cubic inches. If you want to convert this to gallons, there are about 231 cubic inches in a gallon, so the tank would hold approximately 16.24 gallons of water.
how hot is the boiling water? That makes a big difference? (is that a homework question?) I'm just trying to apply logic here, bear in mind there may be some special properties that you may have to account for like the glass/plexiglas that the water is in will have to have its temp raised also. So here goes... Raising 500 gallons of water 20 degrees would seem to require a combined value of 10,000 degrees (500 gallons times 20 degrees). So first you need to know the temperature difference between the existing water and boiling. Then devide the resulting difference into the 10,000 degrees for your simplistic answer. However, it is a bit more complicated if the tank is full at 500 gallons because you have no room to add the boiling water. That is, it would roughly take 62 gallons of boiling water to raise 500 gallons of 50 degree water to 70 degrees and the tankwouyld obviously overflow. So if it was already full you would have had to remove 62 gallons first leaving 438 gallons and consequently reducing your degree needs to 8760 degrees which means if you add the 62 gallons of boiling water you would have ended up with 72.7 degree water. So, I'd reduce the capacity to 445 gallons and add 55 gallons of boiling water and you should be pretty close.
To cool 30000 gallons of water by 5-8 degrees, you would need approximately 215-320 pounds of dry ice. Each pound of dry ice can cool about 10 gallons of water by 1 degree. So, for a 5-8 degree temperature drop in 30000 gallons of water, you would need to use 215-320 pounds of dry ice.
The time it takes for 10 gallons of water to freeze at -0.5 degrees Celsius depends on various factors such as the starting temperature of the water, the container material, and the surrounding environment. Generally, it could take several hours to overnight for water to freeze at that temperature.
Suppose G gallons are used. Before mixing, you have 5*65 + G*120 = 325 + 120G gallon-degrees. After mixing, you have (5+G)*70 gallon-degrees So 325 + 120G = (5+G)*70 = 350 + 70G So 50G = 25 G = 0.5 gallons.
The number of pounds in a gallon of water changes with temperature. At 100 degrees Celsius, there is about 8 lbs. per gallon of water. So with one thousand lbs. of steam, we would have around 125 gallons of water.
200 gallons of water would weigh approximately 1,667 pounds.
There are approximately 224 gallons of water in 1 ton. Therefore, 150 tons of water would be around 33,600 gallons.
230 pounds of water would be equal to approximately 27.6 gallons.
600 pounds of water is equivalent to approximately 71.6 gallons.
If a pool was leaking for 12 hours and leaked out 78 gallons of water in total, then it would of leaked out 6.5 gallons every hour. This is a math problem.
Of water no. Water would be about 32 pounds in 4 gallons.
Five gallons of sand would actually weigh more than five gallons of water.
