Answer:
The minimum size aluminium equipment grounding conductor required is 4 AWG.
Explanation:
minimum aluminum size = 125/0.8
= 156.25
Therefore, The minimum size aluminium equipment grounding conductor required is 4 AWG.
Answer:
S = 172.69 J/K
Explanation:
For a closed system, the entropy is given as the natural logarithm of microstates.
The number of particles (grains of sand); N = 25
The number of boxes (compartments); M = 1000
Entropy is the logarithm of number of microstates; Thus,
S = In ψ
However, the number of microstates is given by the formula;
ψ = Mⁿ
Thus, S = In Mⁿ
Plugging in the relevant values to obtain;
S = In (1000)^(25)
S = 172.69 J/K
Answer:
Applied science is the application of existing scientific knowledge to practical applications, like technology or inventions. Within natural science, disciplines that are basic science develop basic information to predict and perhaps explain and understand phenomena in the natural world.
A) The pressure (p)=400kPa=0.400MPa
Mass of mixture =M
quality (X)= 0.60
Volume of mixture (V)=10 m3
From steam table at P=0.400MPa
Specific volume of saturated water (vf)=0.00108355 m3/kg
Specific volume of saturated steam (vg)=0.46238 m3/kg
Therefore, the volume of steam having X=0.6 is given by
V=M[vf+X(vg-vf)]
10= M[0.00108355+0.6(0.46238-0.00108355)]
M=36.04748 kg
If pressure is lowered to 300kPa
p=0.300MPa
From steam table we get,
Specific volume of saturated water (vf)=0.00107317 m3/kg
Specific volume of saturated steam (vg)=0.60576 m3/kg
Therefore, the volume of steam having X=0.6 is given by
V=M[vf+X(vg-vf)]
10= M[0.001007317+0.6(0.60576-0.00107317)]
M= 26.4825 kg
