What is the BTU required to raise the temperature of 10 pounds of water from 50 degrees to 70 degrees?

200 BTU. I'm assuming your temperatures are in Fahrenheit, since all of your other measurements are in the Imperial system. A BTU is defined as the amount of energy required to raise the temperature of 1 pound water by 1 degree F, so the temperature is raised by 20 degrees, and 10 pounds of water: 20 x 10 = 200


How much energy is required to raise 160 cfm of air from 10 to 170 degrees f?

The amount of energy that is required to 160 cfm of air from 10 to 170 degrees F is 200 btu. T he formula is weight x specific heat x temperature difference so we have10 pounds x 1.00 x 2010 for 10 pounds of water.


How much heat must be removed from 10 pounds of 32 degree water to turn it into 10 pounds of ice at 32 degrees?

We must first know the heat of fusion of water, which is the required energy to melt a given quantity of ice. For water, this is 334 J/g. 334 Joules have to be applied to one gram of 32°F ice to melt it, so 334 Joules have to be taken out of one gram of 32°F water to freeze it. 10 pounds is 4,535.9237 grams, so (4,535.9237) * 334 gives us 1,514,998.52, the amount of energy in Joules that has to be removed from 10 pounds of water to freeze it. The final answer is 1.51499852 MJ (megajoules)


How many btu does it take to raise the temperature of 1 gallon of water 1 degree if water was already 50 degrees?

U.S.gallon = 8.33 pounds of water. Therefore to raise the temperature by one degree F will require 8.33 BTU. The initial temperature of 50 F is inconsequential.

How many degrees to water weight 7975 pounds?

To convert 7975 pounds of water weight into degrees, you need to know the temperature in which the water is being measured. Degrees typically refer to temperature, not weight, so more information is needed to provide an accurate conversion.


Cubic foot of water weighs?

The amount that a cubic foot of water weighs depends on the temperature of the water. At 70 degrees F. a cubic foot of water weighs 62.50 pounds.


How much does a gallon of water weight at 229 degrees?

The weight of a gallon of water at 229 degrees Fahrenheit would be approximately 8.33 pounds. This is because water's density changes with temperature, and at 229 degrees Fahrenheit, water is less dense compared to when it is at room temperature.


How many btus are required to raise the temperature of 15 pounds of water from 100 degrees fahrenheit to 130 degrees fahrenheit?

To calculate the BTUs required to raise the temperature of 15 pounds of water, you can use the formula: BTUs = Weight of water in pounds × Temperature change in degrees Fahrenheit × 1 BTU So, the calculation would be: BTUs = 15 lbs × (130°F - 100°F) × 1 BTU = 15 lbs × 30°F = 450 BTUs.

What is the BTU formula?

BTUs, or British Thermal Units, measure the amount of heat energy required to raise the temperature of one pound of water by one degree Fahrenheit. The formula to calculate BTUs is: BTUs = weight of water (in pounds) x temperature change (in degrees Fahrenheit) x 1. Alternatively, the formula can be expressed as: BTUs = (Flow rate in gallons per minute x change in temperature in degrees Fahrenheit) / 500.


How heavy in pounds is a a gallon of avgas?

Aviation gasoline (avgas) has an average weight of slightly over 6 pounds per gallon (6.02) at a Standard Day temperature of 15 degrees C or 59 degrees F.

How do you convert a cubic feet of nitrogen to pounds?

You cannot. The amount (mass) of nitrogen in a given volume depends on its pressure and temperature.


Is heat measured in degrees?

No. Heat is one of many forms of energy, and is measured in units of energy ... joules, calories, watt-seconds, BTU, foot-pounds, etc. "Degrees" describe the temperature of an object or a sample of a substance. That's a measure of how "full of heat" it is. One joule of heat will fill an ounce of water higher than the same joule will fill a gallon of water. So after absorbing the same amount of heat, the temperature of the ounce is higher than the gallon's temperature.
