Answer:
The efficiency of this fuel cell is 80.69 percent.
Explanation:
From Physics we define the efficiency of the automotive fuel cell (), dimensionless, as:
(Eq. 1)
Where:
- Maximum power possible from hydrogen flow, measured in kilowatts.
- Output power of the automotive fuel cell, measured in kilowatts.
The maximum power possible from hydrogen flow is:
(Eq. 2)
Where:
- Volume flow rate, measured in cubic meters per second.
- Density of hydrogen, measured in kilograms per cubic meter.
- Heating value of hydrogen, measured in kilojoules per kilogram.
If we know that ,
,
and
, then the efficiency of this fuel cell is:
(Eq. 1)
(Eq. 2)
The efficiency of this fuel cell is 80.69 percent.
Answer:
Bubble sort, sometimes referred to as sinking sort, is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order. The pass through the list is repeated until the list is sorted.
