Answer:
Explanation:
A.)
You just pick values for x, y and z, then work out F for each case. Since you have four variables, the values for x, y and z in your table will be as follows:
w x y z
0 0 0 0
0 0 0 1
0 0 1 0
0 0 1 1
0 1 0 0
0 1 0 1
0 1 1 0
0 1 1 1
1 0 0 0
1 0 0 1
1 0 1 0
1 0 1 1
1 1 0 0
1 1 0 1
1 1 1 0
1 1 1 1
Now just work out F for each case. It would be helpful to add a few extra coloumns since that's a pretty big equation. Here's how I would do it (notice the titles of the columns. I've worked out the first two for you to help you understand)
w | x | y | z | xy'z | x?y?z | w?xy | wx?y | wxy | F
0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0
0 | 0 | 0 | 1 | 0 | 1 | 0 | 0 | 0 | 1

C.)
F = xy'z + x'y'z + w'xy + wx'y + wxy
F = (x+x')(y'z) + w'xy + (x+x')(wy)
F = y'z + w'xy + wy
F = y'z + y(w'x + w)
F = y'z + y(w + x)
F = y'z + wy + xy

Logic Circuits, Boolean Algebra, and Truth Tables
: Truth Tables
A truth table is a chart of 1s and 0s arranged to indicate the results (or outputs) of all possible inputs. The list of all possible inputs are arranged in columns on the left and the resulting outputs are listed in columns on the right. There are 2 to the power n possible states (or combination of inputs). For example with three inputs there are 2^3=8 possible combination of inputs. (Audio)
E)
: Logic Diagram
A logic diagram uses the pictoral description of logic gates in combination to represent a logic expression. An example below shows a logic diagram with three inputs (A, B, and C) and one output (Y). The interpretation of this will become clear in the following sections.
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.
It would be 72cm bc u need to add up all the line in the back to
Answer:
Failure Rate
Explanation:
Failure rate is the frequency with which an engineered system or component fails, expressed for example in failures per hour.
It is often denoted by the Greek letter λ (lambda) and is important in reliability theory.
Failure rate is usually time dependent, and an intuitive corollary is that the rate changes over time versus the expected life cycle of a system
Answer:
1. 640.09 KJ/kg
2. 3025.232 KJ/kg
3. 272.09 KJ /kg
4. m3 = 9.624 kg /s
5. m5 = 62.37 kg/s
Explanation:
part a
P6 = 5 bar @saturated liquid
Use table A-5
[email protected] 5bar = h_f,5bar = 640.09 KJ/kg
part b
T3 = 281 C ... super-heated steam
P6 = 500 KPa ... Tsat,@500 KPa = 151.83 C
Use table A-6
P = 0.5 MPa ......
T = 250 C , h = 2961 KJ/kg
T = 300 C , h = 3064.6 KJ/kg
Interpolate:
m = (3064.6 - 2961) / (300 - 250) = 2.072
c = 3064.6 - 2.072*300 = 2443
h3 = 2.072*281 + 2443 = 3025.232 KJ/kg
part c
T5 = 65 C .... compressed liquid
P6 = 500 KPa ... Tsat,@500 KPa = 151.83 C
Use Table A-4
[email protected] C, f = 272.09 KJ /kg
part d and e
Continuity Equation
m3 + m5 = m_exit = 72 kg /s .... Eq 1
Energy balance:
m3*h3 + m5*h5 = m_exit * h_exit .... Eq 2
3025.232*m3 + 272.09*m5 = 72*640.09 = 46086.48 .... Eq 2
Solve above two equation simultaneously for
m3 = 9.624 kg /s
m5 = 62.376
