To Find: The time for which cylinder will last.
Answer to Problem 85GP
The time up to which the cylinder last for a given flow rate is
Explanation of Solution
Given info:
Gauge pressure,
Volume,
Temperature,
Flow rate,
Cylinder giving out oxygen to some hospital at a rate of 2.4 lit/min at following condition.
Gauge pressure,
Volume,
Temperature,
Formula used:
Write the expression for ideal gas law.
Write the expression for number of molecule escape per minute.
Here,
Calculation:
Substitute the given values in the above equations,
For the Volume of
For the Volume of 2.4 L, number of molecules are
The total 90 moles in the cylinder and there are 0.099 moles are releasing every minute. So, the total time that the cylinder last is calculated by following way,
Conclusion:
Thus, the time up to which the cylinder last for a given flow rate is
