Answer:
MRR = 1.984
Explanation:
Given that
Depth of cut ,d=0.105 in
Diameter D= 1 in
Speed V= 105 sfpm
feed f= 0.015 ipr
Now the metal removal rate given as
MRR= 12 f V d
d= depth of cut
V= Speed
f=Feed
MRR= Metal removal rate
By putting the values
MRR= 12 f V d
MRR = 12 x 0.015 x 105 x 0.105
MRR = 1.984
Therefore answer is -
1.944
Answer:

Explanation:
Given
Airline flying at 34,000 ft.
Cabin pressurized to an altitude 8,000 ft.
We know that at standard condition ,density of air

We know that pressure difference
ΔP=ρ g ΔZ
Here ΔZ=34,000-8,000 ft
ΔZ=26,000 ft

ΔP=0.074 x 32.2 x 26,000

So pressure difference will be
.
Answer:
conditional instability (Γd > Γe > Γw)
Explanation:
Given;
dry adiabatic rate, Γd = 10ºC/1000 meters
wet adiabatic rate, Γw= 6.5ºC/1000 meters
environmental lapse rate, Γe = 7.8ºC/1000 meters
Stability of the atmosphere can be described as Absolute stability, Absolute instability or conditional instability.
Conditions for Absolute stability:
Γd > Γw > Γe
Conditions for Absolute instability:
Γe > Γd > Γw
Conditions for conditional instability:
Γd > Γe > Γw
Thus, conditional instability satisfies the given values of the atmospheric condition: Γd (10) > Γe (7.8) > Γw (6.5)
