There are approximately 4 × 10⁴ BTU per liter of crude oil.
BTU is a measure of energy. It is like the unit calorie. It is a measure of the amount of energy needed to increase the temperature of one pound of water by one degree Fahrenheit
This is a simple dimensional analysis problem. To solve the problem, we first sort the given to get the following relationships:
1 barrel = 6,000,000 BTUs
1 L = ? BTU
In order to get the desired quantity, the conversion from barrel to liters must be known. The relationship is 1 barrel = 159 L.
With these information, we can set up the dimensional analysis as shown below:
[tex]BTU \ per \ liter \ = \frac{6 \times \ 10^6 BTU}{1 \ barrel} \times \frac{1 \ barrel}{159 \ L}\\\\\boxed {BTU \ per \ liter \ = 37,735.85 \ \frac{BTU}{L}}[/tex]
Since the given only has one significant digit, the final answer must also have one. Therefore, rounding off to one significant figure. the final answer is:
Keywords: barrel, BTU, L
