Answer:
maximum temperature = 1322 k
rate of heat addition = 212 kw
Explanation:
compression ratio = 17
cut off ratio = 1.3
power produced = 140 Kw
state of air at the beginning of the compression = 90 kPa and 578 c
Determine the maximum temperature of air
attached below is the detailed solution
Answer:
Circular tube
Explanation:
Now for better understanding lets take an example
Lets take
Diameter of solid bar= cm
Outer diameter of tube =6 cm
Inner diameter of tube=2 cm
So from we can say that both tubes have equal cross sectional area.
We know that buckling load is given as
If area moment of inertia(I) is high then buckling load will be high.
We know that area moment of inertia(I)
For circular tube
For circular bar
Now by putting the values
For circular tube
For circular bar
So we can say that for same cross sectional area the area moment of inertia(I) is high for tube as compare to bar.So buckling load will be higher in tube as compare to bar.
Answer:
The required wall thickness is m
Explanation:
Given:
Fluid density
Diameter of tank m
Length of tank m
F.S = 4
For A-36 steel yield stress MPa,
Allowable stress
MPa
Pressure force is given by,
Pa
Now for a vertical pipe,
Where required thickness
m
Therefore, the required wall thickness is m
