Answer:
Explanation:
First we compute the characteristic length and the Biot number to see if the lumped parameter
analysis is applicable.
Since the Biot number is less than 0.1, we can use the lumped parameter analysis. In such an
analysis, the time to reach a certain temperature is given by the following
From the data in the problem we can compute the parameter, b, and then compute the time for
the ratio (T – T)/(Ti
– T)
Answer:
Absolute pressure= 57 KPa
Explanation:
Given that
Vacuum gauge pressure = 35 KPa
Atmospheric pressure = 92 KPa
We know that
Absolute pressure=Atmospheric pressure + gauge pressure
But we should remember that Vacuum gauge pressure is also called negative gauge pressure.So when given that pressure is vacuum gauge then subtract gauge pressure from atmospheric pressure instead of addition.
So now by putting the values
Absolute pressure=Atmospheric pressure - Vacuum gauge pressure
Absolute pressure=92 - 35 KPa
Absolute pressure= 57 KPa
Sorry bro people do this22.2 pls
Answer:
The fluid level difference in the manometer arm = 22.56 ft.
Explanation:
Assumption: The fluid in the manometer is incompressible, that is, its density is constant.
The fluid level difference between the two arms of the manometer gives the gage pressure of the air in the tank.
And P(gage) = ρgh
ρ = density of the manometer fluid = 60 lbm/ft³
g = acceleration due to gravity = 32.2 ft/s²
ρg = 60 × 32.2 = 1932 lbm/ft²s²
ρg = 1932 lbm/ft²s² × 1lbf.s²/32.2lbm.ft = 60 lbf/ft³
h = fluid level difference between the two arms of the manometer = ?
P(gage) = 9.4 psig = 9.4 × 144 = 1353.6 lbf/ft²
1353.6 = ρg × h = 60 lbf/ft³ × h
h = 1353.6/60 = 22.56 ft
A diagrammatic representation of this setup is presented in the attached image.
Hope this helps!
Answer:
44027.28 Joules
Explanation:
We know that Potential Energy of a body of mass 'm' is given by
where
g= acceleration due to gravity with value = 9.81
h = height above the ground level
Applying given values in the formula we get
Thus
