how many btu's in 350 gal of water at both 80 &240 degrees
To calculate the BTUs (British Thermal Units) in 350 gallons of water at both 80 and 240 degrees Fahrenheit, we need to consider the specific heat capacity of water and the temperature change.
1. Calculate the BTUs at 80 degrees Fahrenheit:
The specific heat capacity of water is approximately 1 BTU/lb °F. Since 1 gallon of water weighs about 8.34 lbs, we can calculate the total weight of water as follows:
350 gallons × 8.34 lbs/gallon = 2919 lbs
Next, we need to calculate the temperature change from 80 degrees to the standard reference temperature of 60 degrees Fahrenheit:
80 - 60 = 20 degrees
To find the BTUs, we multiply the weight of water by the temperature change and the specific heat capacity:
2919 lbs × 20 degrees × 1 BTU/lb °F = 58,380 BTUs
Therefore, there are 58,380 BTUs in 350 gallons of water at 80 degrees Fahrenheit.
2. Calculate the BTUs at 240 degrees Fahrenheit:
Perform the same calculations using the new temperature of 240 degrees Fahrenheit:
Temperature change: 240 - 60 = 180 degrees
BTUs = 2919 lbs × 180 degrees × 1 BTU/lb °F = 947,220 BTUs
Thus, there are 947,220 BTUs in 350 gallons of water at 240 degrees Fahrenheit.
