Question

Объём 1 т нефти -7,3 барреля, переработка 1 т нефти стоит 50 долл , из 1 т нефти получают 9000 л бензина ; переработка 1т кукурузы в этиловый спирт обходятся в 100 долл ,из 20 кг получают 100 л этилового спирта . Какой вид моторного топлива - бензин или этиловый спирт - выгоднее использовать США , если считать, что при сжигании 1 л бензина и 1 л этилового спирта выделяется одинаковое колличество энергии, 1 баррель нефти стоит 50 долл., а 1 т кукурузы (сырья для производства этилового спирта ) - 1500 долл.?

Answer 1

Все проаналізувавши, думаю, що для США краще виробляти бензин, дешевше виходить і більше.

Answer 2

Calculation of Fuel Efficiency

To determine which type of motor fuel is more cost-effective to use in the United States, we need to compare the costs and energy outputs of gasoline and ethanol.

Given the following information: - The cost of processing 1 ton of crude oil into gasoline is $50, and it yields 9,000 liters of gasoline. - The cost of processing 1 ton of corn into ethanol is $100, and it yields 100 liters of ethanol.

We also know that burning 1 liter of gasoline and 1 liter of ethanol releases the same amount of energy.

To make a comparison, we need to calculate the cost of producing 1 liter of each fuel type.

Calculation for Gasoline:

- 1 ton of crude oil yields 9,000 liters of gasoline. - The cost of processing 1 ton of crude oil into gasoline is $50. - Therefore, the cost of producing 1 liter of gasoline is $50/9,000 = $0.0056 per liter.

Calculation for Ethanol:

- 1 ton of corn yields 100 liters of ethanol. - The cost of processing 1 ton of corn into ethanol is $100. - Therefore, the cost of producing 1 liter of ethanol is $100/100 = $1 per liter.

Comparison:

Based on the calculations, we can see that the cost of producing 1 liter of gasoline is significantly lower than the cost of producing 1 liter of ethanol. Therefore, gasoline would be more cost-effective to use as motor fuel in the United States.

Please note that this analysis only considers the cost of production and does not take into account other factors such as environmental impact or government subsidies.
