Answer:
a)P-v
Explanation:
Isobaric:
Isobaric process is a process in which initial and final pressure will be same.This is also called constant pressure process.
If we take a process in which pressure is constant then there will be two possibility maybe this is compression process or maybe this is expansion pressure depending on the given condition.
In general only in P-v diagram ,isobaric processes are represented by straight lines.
If we take a saturated steam ,in which on T-s diagram pressure lines are represented by straight lines.
If we take the ideal gas Pv= mRT if we fix pressure then T-v digram will be linear diagram so we can say that here is also isobaric processes are represented by straight lines.
But from above most appropriate answer will be a.
Answer: The function of an electric switch is to regulate the current between the load and source of the power. The power source is the electrons that push through the circuits. ... The load receives the current and returns it via the positive terminal to the power source. The electrical switch is inserted

Answer:
Explanation:
Diffusion flux of a gas, J is given by
where is permeability coefficient, P is pressure difference and x is thickness of membrane.
The pressure difference will be 10,000 Pa- 3000 Pa= 7000 Pa
At 298 K, the permeability coefficient of water vapour through polypropylene sheet is
Since the thickness of sheet is given as 1mm= 0.1 cm then
Therefore, the diffusion flux is
Answer:
(A) Dry unit weight. = 15.71 kN/m³ =100.91 pcf
(B) Porosity = 40.82 %
(C) Degree of saturation = 66.52 %
(D) Weight of water, in pounds per cubic foot, to be added to reach full saturation = 81.22 pcf
Explanation:
(A) γd = = KN/m³
(B) therefore 1.69
Therefore e = 0.69 and
Porososity n = = × 100% = 40.82 %
(C) therefore S = = ×100 = 66.52 %
(D) = = 19.68 kN/m³
The required amount of water is found from γ =ρ×g
ρ mass of water =
1 kg/m³ = 0.062 pcf therefore 1301 kg/m³ = 1301 ×0.062 pcf or 81.22 pcf
