Answer:
7557120 kg/hour
Explanation:
Given data;
Volume of air in one second = 1640 L
Density of air = 1.28 kg/L
Mass of air in 1 hour =?
Since mass = density × volume
==> Mass of air in one second = 1.28 ×1640 = 2099.2 kg
==> Mass of air in one minute = 2099.2×60=125952 kg
==> Mass of air in one hour = 125952× 60 = 7557120 kg
So rate of flow of air is 7557120 kg/hour

Explanation:
The work done by the gas is given by:
where
p is the gas pressure
is the final volume of the gas
is the initial volume
We must convert all the quantities into SI units:
So the work done is
