Find the amount of natural gas needed to burn to heat twenty gallons of water.
Answer to Problem 1P
The amount of natural gas needed to burn to heat twenty gallons of water is
Explanation of Solution
Calculation:
The volume of used natural gas depends upon the rise of temperature and the efficiency of the heater. Typically, the heating value of the natural gas ranges from
Therefore, assume that the heating value of natural gas is
Convert the twenty gallons of water into pound.
The specific heat capacity of water is
Hence, the volume of natural gas used is,
Therefore, the amount of natural gas needed to burn to heat twenty gallons of water is
Conclusion:
Thus, the amount of natural gas needed to burn to heat twenty gallons of water is
