Answer:De Morgan's theorem

De Morgan's theorem states (Equation 1.16) that complementing the result of OR'ing variables together is equivalent to AND'ing the complements of the individual variables. Also (Equation 1.17), complementing the result of AND'ing variables together is equivalent to OR'ing the complements of the individual variables.

Example 1.9

Use Boolean algebra and de Morgan's theorem for two variables,

A+B

⋅

, to show that the form given in Equation 1.16 for three variables is also true.

Solution

Draw the circuits that will perform the functions described by both sides of the first of De Morgan's theorems (Equation 1.16) given in Table 1.4, and also demonstrate the theorem is true using a truth table.

Montano1993 [528]

Answer

diameter of parking lot = 18 in

flowrate = 10 ft³/s

pressure drop = 100 ft

using general equation

$\dfrac{P_1}{\gamma}+\dfrac{v_1^2}{2g}+Z_1 = \dfrac{P_2{\gamma} + \dfrac{v_2^2}{2g} + Z_2 +\dfrac{fLV^2}{2\rho D}$

$V = \dfrac{Q}{A} = \dfrac{10}{\dfrac{\pi}{4}(\dfrac{18}{12})^2} = 5.66\ ft/s$

$\Delta P = \gamma (Z_2-Z_1) +\dfrac{fLV^2}{2\rho D}$

taking f = 0.0185

at Z₁ = Z₂

$\Delta P = \dfrac{0.0185 \times 100\times 1.94\times 5.66^2}{2\dfrac{18}{12} (2)}$

ΔP = 0.266 psi

b) when flow is uphill z₂-z₁ = 2

$\Delta P =62.4\times 2 \times \dfrac{1}{144} +0.266$

$\Delta P= 1.13\ psi$

c) When flow is downhill z₂-z₁ = -2

$\Delta P =62.4\times 2 \times \dfrac{1}{144} +0.266$

$\Delta P=-0.601\ psi$

Determine the phase or phases in a system consisting of H2O at the following conditions and sketch p-v and t-v diagram showing t

aivan3 [116]

Answer:

Explanation:

We will use the water property tables at respective states. Using Tables A-3, A-2, and A-5.

Part a

P = 10 bar and T = 179.9

From tables we find that the T saturated is also 179.9; Hence, the H20 exist in a two phase liquid-vapor mixture. T = [email protected]

For p-v and T-v see attachment 1

Part b

P = 10 bar and T = 150

From tables we find that the T saturated is 179.9; Hence, the H20 exist in the sub-cooled liquid region. T < [email protected]

For p-v and T-v see attachment 2

Part c

P = 0.5 bar and T = 100 C

From Temperature tables we find that the P saturated is 1.014 bar; Hence, the H20 exist in the super-heated region. P < [email protected] Table A-2

For p-v and T-v see attachment 3

Part d

P = 50 bar and T = 20 C

From Temperature tables we find that the P saturated is 0.02339 bar; Hence, the H20 exist in the sub-cooled liquid region. P > [email protected] Table A-2

For p-v and T-v see attachment 4

Part e

P = 1 bar and T = -6 C

From Temperature tables we find that the P saturated is 0.003689 bar; Hence, the H20 P > [email protected] solid because T is below triple point Temperature. Table A-5

Sever21 [200]

Answer:

The correct answer to the following question will be " $a_{x}$ or $a_{y}$ ".

Explanation:

Since along that same z-axis none electromagnetic field would be triggered as being in the same orientation loop movement of them across different line portions would allow some caused emf/voltage to be canceled. And the only logical choice seems to be either x or y-axes.
The magnetic field of fluctuation should indeed be changed and changed across both X as well as Y directions.

So that the above is the appropriate choice.
