Question

At 20% efficiency, how many kWh would actually be produced from the 5 gal of gasoline? How

many BTUs of heat would be released from burning the gasoline?

Answer 1

5 gallons of gasoline at 20% efficiency would produce 185 kWh of energy. The burning of the gasoline would release approximately 617,489 BTUs of heat.

Step-by-step explanation:

To calculate the amount of kWh produced from 5 gallons of gasoline at 20% efficiency, we need to multiply the energy content of one gallon of gasoline (37 kWh) by the number of gallons (5). This gives us a total of 185 kWh.

To calculate the amount of BTUs of heat released from burning the gasoline, we need to multiply the energy content of one gallon of gasoline (130 MJ) by the number of gallons (5) and convert it to BTUs. This gives us a total of approximately 617,489 BTUs.

Answer 2

Answer:c. At 20% efficiency, how many kWh would actually be produced from the 5 gal of gasoline? How many BTUs of heat would be released from burning the gasoline? (3 points) 1.3 x 10 J x 1 kWH / 3.6 x 10 J = 36.1 kWh 5.2 x 10 J x 1 BTU / 1055 J = 492891 BTU 36.1 kWh would actually be produced from 5 gallons of gasoline.
