How much ice is needed to lower the temperature of a pool?

How much ice is needed to lower the temperature of a pool?

Taking both steps together, one pound of ice will absorb about 48,000 calories in the process of becoming 80° pool water. So to lower the temperature of a 20,000 gallon pool of 90 degree water by 10 degrees, you would need about 8,750 pounds of ice.

How much ice does it take to cool a pool?

When dry ice is exposed to water it goes directly from a solid to a gas and that gas dissipates too quickly to really cool the water. By comparison, it would take, depending on what you read, somewhere between 500 and 1,000 pounds of real ice to cool an average size pool by 5 degrees.

How much ice makes a gallon of water?

The density of ice is 0.9167 g/cm³. The ratio of volumes is inversely proportional to the ratio of densities. So, for example, one gallon of water near the freezing point would make the equivalent of 1.090 gallons of ice.

Can I cool down my pool with ice?

Ice. Ice can also cool a pool, but it is really not a practical method of cooling pool water—as it takes an excessive amount of ice and the change is only temporary. According to an article in the Wall Street Journal, it would take 8,750 pounds of ice to lower the water temperature of a 20,000 gallon pool by 10 degrees …

What is the fastest way to cool down a pool?

How to Cool Down a Swimming Pool

1. Run Your Filter at Night. The most practical one is to run your filter at night when the air is cooler.
2. Cool Your Pool Down with Ice. Of course!
3. Remove Landscaping.
4. Install a Reverse-Cycle Heat Pump.
5. Use Your Solar Heater.
6. Install a Water Fountain.

How do you calculate the mass of ice needed to cool water?

Use the law of conservation of heat or equate the heat gained by the ice and the heat gained by the water and calorimeter to get the mass of ice required. Hgained by ice = Heatlost by the calorimeter and the water. Thus we found the mass of the ice using the law of conservation of heat energy as 50g.

Can you use dry ice to cool a pool?

CAN I COOL A POOL WITH DRY ICE? Great for adding a spooky fog on the surface of the pool, but not so good for lowering pool water temperature. “Dry Ice evaporates into a gas as it cools, not into water – having very little effect on pool water temperature”, he said.

How do I cool down the temperature of my pool?

Following are some methods that have been used to lower the temperature of their pool water:

1. Fountains & waterfalls.
2. Ice.
3. Drain & refill.
4. Shade the pool.
5. Reversible heat pumps.
6. Evaporative coolers.
7. Cooling the pool area.

How much water does it take to make 100lbs of ice?

Commercial ice-makers typically use 15 to 25 gallons of water to produce 100 pounds of ice flakes or cubes, depending on the quality of the ice. Older water-cooled ice machines may use as much as 90 gallons to produce the same quantity of ice.

Does a gallon of water weight the same as a gallon of ice?

No, water and ice do not weigh the same. For example, if we take the same volume of water and ice in the same container, water would weigh more than ice. Therefore, ice floats on water since its density is less than that of water.

Can you cool down a pool with ice?

How much ice would it take to cool a swimming pool?

“So to lower the temperature of a 20,000 gallon pool of 90 degree water by 10 degrees, you would need about 8,750 pounds of ice. A ten-pound bag of ice costs around a buck, so cooling your pool with ice cubes would cost $875. (It would also add about 3 inches to the depth of the water.)

How many BTU to change temp of ice?

The temp of ice is important because it only takes about 0.5 btu to change the temp of ice 1 deg F. (0.5 btu required to change the temp of 1 lb. of water vapor 1 deg F also.) I must brush up on my math to solve your problem..heh..heh. 12000 btu PER HOUR will change 1 ton of 32*F ice to one ton of 32*F water in 24 hours.

How much heat does one ton of ice need?

Up or down you have 1BTU per 1LB per 1Deg F until you start changing state with your water. SO… Your 1F temp change in your 8.33lb (1 usg) of water requires 8.33BTU. The 12,000BTU you are refering to is the LATENT heat of conversion of one ton of Ice at 32F to one ton of water at 32F.

How much water does a lb of ice take?

Each lb. of ice must take in 144 btu to change to 32* water. Each lb. must then take on 63 btu to raise temp. to 95* (95-32=63). Each lb. will take (144+63)or 207 btu. 26,656/207=128.773 Lb. of ice. I still haven’t allowed for other than 8.33 lb./gal.
