Answer:B
Explanation: Dead Grass more flammable than wood and Green grass contains water.
Jack Plane is designed to take off heavy shavings and squares up rough timber to correct size and quickly removes waste wood.
Answer:
T=194.3C
X=1
P=542.5kPa
Explanation:
Through laboratory tests, thermodynamic tables were developed, these allow to know all the thermodynamic properties of a substance (entropy, enthalpy, pressure, specific volume, internal energy etc ..)
through prior knowledge of two other properties
First we find the specific volume knowing the temperature and quality of state 1
v(p=400kPa, x=0.75)=0.3471m^3/kg
As a constant volume process is presented, it keeps constant in state 2, so we find the temperature and quality with p = 600kPa and v = 0.3471m ^ 3 / kg
T(P=600kPa, v=0.3471m ^ 3 / kg)=194.3C
x(P=600kPa, v=0.3471m ^ 3 / kg)=1
for the second part we find the pressure, with a quality of 1 and a volume of
v= 0.3471m ^ 3 / kg
p=542.5kPa
Answer:
point B where has the largest Q value at section a–a
Explanation:
The missing diagram that is suppose to be attached to this question can be found in the attached file below.
So from the given information ;we are to determine the point that has the largest Q value at section a–a
In order to do that; we will work hand in hand with the image attached below.
From the image attached ; we will realize that there are 8 blocks aligned on top on another in the R.H.S of the image with the total of 12 in; meaning that each block contains 1.5 in each.
We also have block partitioned into different point segments . i,e A,B,C, D
For point A ;
Let Q be the moment of the Area A;
SO ;
where ;
For point B ;
Let Q be the moment of the Area B;
SO ;
where ;
For point C ;
Let Q be the moment of the Area C;
SO ;
where ;
For point D ;
Let Q be the moment of the Area D;
SO ;
since there is no area about point D
Area = 0
Thus; from the foregoing ; point B where has the largest Q value at section a–a
It’s not because the steering is better or the brakes are on the right sensitivity. It’s because for some reason, you don’t hear anything else but the engine running. Nothing but the purr of the engine in idle or the roar when you accelerate. No clickety clanks or hard, metal-on-metal noise that makes you feel like your car will get disassembled anytime soon.
