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 
<u>Explanation</u>
The Iron is incontact with the shirt. So, heat is transferred from the iron to the shirt because they are in contact.
Before the contact, there is temperature difference between the shirt and the iron. When they come into contact there must be exchange of heat energy, this happens until equilibrium state is reach.
Let us say that triangle XYZ has sides of XY, YZ, and ZX.
Each of the corners X, Y, and Z are located at their own
(x, y) points.
If all of the triangle are transformed through
translation by a movement of 2 units left and 1 unit down on the coordinate
plane then we generate a triangle X’Y’Z’.
Then each of the corners X’, Y’ and Z’ are now located at
(x – 2, y – 1) coordinates.
Since all of the corners were moved then we can also say
that:
XY is congruent to X’Y’
YZ is congruent to Y’Z’
ZX is congruent to Z’X’
Since all sides are congruent, therefore all angles are
also congruent.
Therefore the measure of angle x’ is equal to the measure
of angle x.
