Answer:
If the tapered roller bearing clearance is too tight, the components will bind and overheat due to increased pressure and because the rollers squeeze out too much grease, making the lubricating film too thin.
Explanation:
Answer:
work=281.4KJ/kg
Power=4Kw
Explanation:
Hi!
To solve follow the steps below!
1. Find the density of the air at the entrance using the equation for ideal gases
where
P=pressure=120kPa
T=20C=293k
R= 0.287 kJ/(kg*K)=
gas constant ideal for air
2.find the mass flow by finding the product between the flow rate and the density
m=(density)(flow rate)
flow rate=10L/s=0.01m^3/s
m=(1.43kg/m^3)(0.01m^3/s)=0.0143kg/s
3. Please use the equation the first law of thermodynamics that states that the energy that enters is the same as the one that must come out, we infer the following equation, note = remember that power is the product of work and mass flow
Work
w=Cp(T1-T2)
Where
Cp= specific heat for air=1.005KJ/kgK
w=work
T1=inlet temperature=20C
T2=outlet temperature=300C
w=1.005(300-20)=281.4KJ/kg
Power
W=mw
W=(0.0143)(281.4KJ/kg)=4Kw
Answer:
i) 125 * 10^9 i
ii) 5.2 ns
iii) 4.8 ns
Explanation:
i) The throughput of the processor for an unpipelined processor
= = 125 * 10^9 instructions per set
ii ) for a 10-stage pipeline
1st instruction :
= 0.2 + 8ns/10
= 0.2 + 0.8 = 1ns
2nd instruction
= 0.2 + 1 + 4
= 5.2 ns
iii). for a 20-stage pipeline
1st instruction
= 0.2 + 8ns/20
= 0.2 + 0.4 = 0.6 ns
2nd instruction
= 0.2 + 0.6 + 4
= 4.8 ns
Answer:
True
Explanation:
The hyperbolic elements for the spacecraft Voyager 1 launched by NASA in 1977 flew by Jupiter and Saturn and continued to explore beyond the solar system into the interstellar space. Trajectory engineers produced data on this journey that indicated a value of eccentricity less than 1 from Earth reaching Jupiter and an eccentricity value greater than 1 for the journey past Jupiter that increases positively as the spacecraft advances to reach Saturn and beyond.
