How many btus of heat are removed per hour when the water at a flow rate of 10 lbs per minute is cooled 15 degrees?
To calculate the BTUs removed per hour, you can use the formula: BTUs = flow rate (lbs/min) × temperature change (°F) × 1. If the flow rate is 10 lbs/min and the temperature change is 15°F, the calculation is: 10 lbs/min × 15°F × 1 BTU/lb°F = 150 BTUs/min. To find the hourly rate, multiply by 60 minutes, resulting in 9,000 BTUs per hour.
Which has the larger value C or F?
A temperature change by one degree on Celsius scale equals temperature change of 1.8 degree on Fahrenheit scale or F (Fahrenheit) = 1.8 C (Celsius) + 32
How much heat required for chainge temp of 28lbs of ice from -38 deg f to 32 deg f?
To calculate the heat required to change the temperature of 28 lbs of ice from -38°F to 32°F, we need to consider both the specific heat of ice and the phase change. The specific heat of ice is about 0.5 BTU/lb°F. First, we raise the temperature of the ice from -38°F to 32°F, which is a 70°F increase. The heat required for this temperature change is approximately 28 lbs × 0.5 BTU/lb°F × 70°F = 980 BTU.
How much did the temperature change in Minneapolis if it was negative 7 F at 6 am and 7 F at noon?
It changed by 14 Fahrenheit degrees.
What was the average change in temperature per hour one day at 3 a.m. the temperature was -13 Fahrenheit in Kodiak Alaska at 10 the temperature was 22 degrees Fahrenheit?
To find the average change in temperature per hour from 3 a.m. to 10 a.m., first calculate the total change in temperature: 22°F - (-13°F) = 35°F. The time span from 3 a.m. to 10 a.m. is 7 hours. Therefore, the average change in temperature per hour is 35°F / 7 hours = 5°F per hour.
How much does air pressure in psi change with temperature changes in degrees F?
Air pressure decreases by about 1 psi for every 10°F increase in temperature. Conversely, air pressure increases by about 1 psi for every 10°F decrease in temperature.
What is the change in temperature for 34F to 67F?
The change in temperature from 34°F to 67°F is an increase of 33°F.
How Many BTU Does 10 gallon of water at 32f to 212f?
To calculate the BTU needed to heat 10 gallons of water from 32°F to 212°F, you can use the formula: BTU = gallons × 8.34 (weight of water per gallon in pounds) × temperature change (in °F). The temperature change is 212°F - 32°F = 180°F. Thus, BTU = 10 gallons × 8.34 lbs/gallon × 180°F = 15,012 BTU.

The temperature dropped 13F in 7 hours the final temperature was -2F what was the starting teperature?
The starting temperature was 11°F. Starting at 11°F, a drop of 13°F in 7 hours would result in a final temperature of -2°F.
What is the formula for c degrees to f degrees?
F = (1.8 * C) + 32 Example: Find Fahrenheit when Celsius = 10 F = (1.8 * 10) + 32 F = 18 + 32 F = 50 10 degrees Celsius is equal to 50 degrees Fahrenheit
Which has the larger value C or F?
A temperature change by one degree on Celsius scale equals temperature change of 1.8 degree on Fahrenheit scale or F (Fahrenheit) = 1.8 C (Celsius) + 32
How many btus are required to change 10 pounds of steam at 212 degrees to 240 degrees?
To calculate the heat energy required to change the temperature of a substance, you can use the formula: Q = mcΔT, where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Given that steam has a specific heat capacity of approximately 0.5 btu/lb°F, you can calculate the required heat energy by plugging in the values: Q = 10 lb * 0.5 btu/lb°F * (240°F - 212°F).
