Answer:
A. 6.36 lbm/s
b. 
Explanation:
a. Given the following information;
#Compressor inlet:
Air pressure,
#Compressor outlet:

#Cooling rate,

# From table A-1E
Gas constant of air 
Specific enthalpy at 
Using the mass balance:

Hence, the mass flow rate of the air is 6.36lbm/s
b The specific enthalpy at the exit is defined as the energy balance on the system:

Hence, the temperature at the compressor exit 
Answer:
the concrete because the concrete absorbs the suns energy, making it hot

The correct answer is:
the distance of the orbiting object to Earth.
In fact, we know that the gravitational force that keeps the object in circular motion around the Earth is equal to the centripetal force, so we can write:
If we re-arrange the equation, we find an expression for the tangential speed of the object:

and we see that it depends on 3 quantities: G, M (the mass of the Earth) and r (the distance of the object from the Earth).

Answer: 757m/s
Explanation:
Given the following :
Mole of neon gas = 1.00 mol
Temperature = 465k
Mass = 0.0202kg
Using the ideal gas equation. For calculating the average kinetic energy molecule :
0.5(mv^2) = 3/2 nRt
Where ;
M = mass, V = volume. R = gas constant(8.31 jK-1 mol-1, t = temperature in Kelvin, n = number of moles
Plugging our values
0.5(0.0202 × v^2) = 3/2 (1 × 8.31 × 465)
0.0101 v^2 = 5796.225
v^2 = 5796.225 / 0.0101
v^2 = 573883.66
v = √573883.66
v = 757.55109m/s
v = 757m/s
