Engineer Kažimír
The TV show example beautifully illustrates the difference between politicians-demagogues and reasonable people with at least primary education.
Engineer Kažimír says that during their tenure, there was a large decline in the price of natural gas. The price went from 0.46 €/m3 to € 0.0425/kWh. Calculate:
Mr. engineer Kažimír does not have a bit of common sense when comparing gas prices in €/kWh to the price quoted €/m3.
Prove that one cubic meter is 46 cents a kilowatt-hour and costs 4.25 cents, so it is the same price.
Engineer Kažimír says that during their tenure, there was a large decline in the price of natural gas. The price went from 0.46 €/m3 to € 0.0425/kWh. Calculate:
- How many percents do the gas price fall if we do not consider the unit in which the price is shown?
- Transform unit 1 kWh of energy to MJ
- If you are considering a calorific value of natural gas was 3.91×107 J/m3, calculate how much MJ is released by burning one cubic meter of gas
- What is the conversion factor combustion heat of natural gas to kWh?
- Calculate how many percent dropped the price of gas when to consider the calorific value gas.
Mr. engineer Kažimír does not have a bit of common sense when comparing gas prices in €/kWh to the price quoted €/m3.
Prove that one cubic meter is 46 cents a kilowatt-hour and costs 4.25 cents, so it is the same price.
