Food and cookware taken out of a microwave oven are rarely much hotter than 100 Â°C (212 Â°F). Cookware used in a microwave oven is often much cooler than the food because the cookware is transparent to microwaves; the microwaves heat the food directly and the cookware is indirectly heated by the food.
Basically cars give better gas mileage on the highway than city street conditions. Typically the gas mileage is 3 to 5 miles more than street driving. So what is considered the best gas mileage for a car is how much more highway gas mileage is over street gas mileages. â¢ Rate and distance-Another way to determine if your car has g ood gas mileage is by calculating your daily driving distances and average rate of speed.
FE = (1/0.15)(15) = 100 miles per gallon. For alternative dual-fuel vehicles, an assumption is made that the vehicles would operate 50% of the time on the alternative fuel and 50% of the time on conventional fuel, resulting in a fuel economy that is based on a harmonic average of alternative fuel and conventional fuel.or example, for an alternative dual-fuel model that achieves 15 miles per gallon operating on an alcohol fuel and 25 mpg on the conventional fuel, the resulting CAFE would be: FE = 1 / [(0.5/25) + (0.5/100)] = 40 miles per gallon. Calculation of fuel economy for natural gas vehicles is similar.
