Question 1.
Convert 568 liters per minute into cubic meters per second.
Show hintHide hint
Remember that 1 liter is 0.001 cubic meters.
Question 2.
What does specific gravity measure?
Show hintHide hint
Think of it as comparing weights.
3Question 3.
What is the flow rate of fuel at 568 liters per minute in cubic meters per second?
- 0.0073
- 0.009467
- 0.00634
Show hintHide hint
Convert liters to cubic meters.
4Question 4.
Is specific gravity a measure of weight?
- True
- False
Show hintHide hint
Think about what it actually measures.
Question 5.
A fighter plane needs to maintain its velocity while refueling from another aircraft. If the internal diameter of the pipe is increased to 0.15 m and flow rate increases to 700 liters per minute, how would the thrust calculation change?
Show hintHide hint
Reapply the principles of continuity and momentum conservation.
Question 6.
Explore how environmental factors like temperature at high altitudes affect the properties of the fuel being transferred. Discuss potential adjustments required in the thrust calculations.
Show hintHide hint
Consider what happens to fluid behavior in varying temperature conditions.
