The acceleration is (144 m^2/s^2) divided by (the radius of the centrifuge).
Answer:
= 829.69 Watt
≅ 830 Watt
Explanation:
Given that,
Velocity of air flow = 12.5m/s
Rate of flow of air = 9m³/s
Density of air = 1.18kg/m³
power by kinetic energy = 1/2(mv²)
mass = density × volume
m = 1.18 × 9
= 10.62 kg/s
power = 1/2 mV²
= 1/2 (10.62 × 12.5²)
= 829.69 Watt
≅ 830 Watt

The efficiency of an ideal Carnot heat engine can be written as:
where
is the temperature of the cold region
is the temperature of the hot region
For the engine in our problem, we have
and
, so the efficiency is
By the isotherm process, the gas will dissolve in 4.5 atm.
It is important to know about isotherm conditions to solve this problem. The isotherm process is a cycle that has the same temperature but different pressure and volume. The process should follow the rule
P1 . V1 =P2 . V2
where P1 is initial pressure, V1 is initial volume, P2 is final pressure and V2 is the final volume.
From the question above, the parameter given are:
P1 = 2 atm
V1 = 1 L
P2 = 4.5 atm
By substituting the parameters to the rule, we get
P1 . V1 =P2 . V2
2 . 1 = 4.5 . V2
V2 = 2 / 4.5
V2 = 0.44 L
Hence, the gas will dissolve in 4.5 atm.
