How many btus must be removed from one pound of water at 200 degrees f for it to end up as ice at 30 degrees f?
313 Btu
How many btus does it take to raise half pound of water 1 degree?
One BTU is the energy required to raise one pound of water by one degrees. Therefore, your answer would be one half.
How many btus are required to convert 1lb ice to 1lb water?
To convert 1 pound of ice at 32°F to 1 pound of water at 32°F, you need to supply 144 BTUs. This energy is required to overcome the latent heat of fusion, which is the energy needed to change ice into water without changing its temperature.
How many Btus of heat are removed per hour when the water at a flow rate of 10 pounds per minute is cooled 15 degrees Fahrenheit (Water weighs 8.33 pounds per gallon)?
To calculate the BTUs removed per hour, use the formula: BTUs = flow rate (lbs/min) × temperature change (°F) × 1.0 (specific heat of water). First, convert the flow rate to pounds per hour: 10 lbs/min × 60 min/hour = 600 lbs/hour. Then, calculate the BTUs: BTUs = 600 lbs/hour × 15°F × 1.0 = 9,000 BTUs/hour. Thus, 9,000 BTUs of heat are removed per hour.
How many BTUs does it take to heat one pound of water from 80 degree F to 212 degree F?
212 - 80 = 132 degrees temperature increase x 1 pound water = 132 BTU
How many btus must be removed from one pound of water at 200 for it to end up as ice at 30?
144
If one pound of water is at a temperature of 32 degrees Fahrenheit, how many BTU’s must be removed in order to create a block of ice at 17 degrees?
LATENT HEAT OF FUSION When one pound of ice melts, it absorbs 144 BTUs at a constant temperature of 32°F. If one pound of water is to be frozen into ice, 144 BTUs must be removed from the water at a constant temperature of 32°F.
How many btus must be removed from one pound of water at 200 degrees f for it to end up as ice at 30 degrees f?
313 Btu
How many Btus must be removed from one pound of water at 200f fro it to end up as ice at 30f?
To determine the BTUs that must be removed from one pound of water at 200°F to convert it to ice at 30°F, we need to account for several steps: cooling the water from 200°F to 32°F (the freezing point), the phase change from water to ice at 32°F, and then cooling the ice from 32°F to 30°F. Cooling the water from 200°F to 32°F requires about 168 BTUs (1 BTU cools 1 pound of water by 1°F). Freezing the water at 32°F requires the removal of 80 BTUs (latent heat of fusion). Cooling the ice from 32°F to 30°F requires an additional 2 BTUs. In total, approximately 250 BTUs must be removed (168 + 80 + 2 = 250 BTUs).
How many btu's in office water-cooler?
There are no BTUs in an office water-cooler. But you can calculate how many BTUs are removed by the cooler. One BTU or British Thermal Unit is the amount of heat energy required to raise the temperature of one pound of water one degree Fahrenheit. There for when you remove one BTU you are lowering one pound of water one degree Fahrenheit. So if you know how many pounds of water you have and the temperature of the water you start with and the temperature of the water comming out of the cooler you can calculate how many BTUs the cooling unit of the water cooler has removed. BTU=Temp1 - Temp 2 X LB water
How many btus are required to change one pound of ice at 20 f to steam at 220 f?
It takes approximately 144 BTUs to change one pound of ice at 20°F to water at 212°F, and an additional 970 BTUs to change the water to steam at 220°F, for a total of 1114 BTUs.
How many btus does it take to turn water into steam?
It takes approximately 970 BTUs to convert one pound of water at 212°F (100°C) to steam at the same temperature.
How many btu's must be removed from one pound of water at 200f for it to end up as ice at 30f?
To convert water at 200°F to ice at 30°F, you need to remove 1 BTU to cool water from 200°F to 32°F to become ice. Then, you need to remove 144 BTUs to cool the ice from 32°F to 30°F. So, total BTUs needed to remove from one pound of water at 200°F to end up as ice at 30°F is 144 + 1 = 145 BTUs.
How many BTUS in 1 pound of steam at 212 degrees Fahrenheit?
One pound of steam at 212 degrees Fahrenheit contains 1150 BTUs of energy.
How many btus does it take to raise half pound of water 1 degree?
One BTU is the energy required to raise one pound of water by one degrees. Therefore, your answer would be one half.
How many btus to heat water 10 degrees?
To raise the temperature of 1 pound of water by 1 degree Fahrenheit, it requires 1 BTU (British Thermal Unit). Therefore, to heat water by 10 degrees, it would require 10 BTUs per pound of water. This value may vary slightly depending on the specific heat capacity of the water.
How many btus are required to convert 1lb ice to 1lb water?
To convert 1 pound of ice at 32°F to 1 pound of water at 32°F, you need to supply 144 BTUs. This energy is required to overcome the latent heat of fusion, which is the energy needed to change ice into water without changing its temperature.
