Answer:
P.E.T
Explanation:
Stud is a short form of stud wall which are typically vertical framing members in a wall of a building. Wall studs are available in standard lengths but since the height of ceiling vary, sometimes one has to cut the stud walls on site to fit. Therefore, there are pre-cut studs which are more efficient in implementation. These are usually referred as Precision-End Trimmed studs, (P.E.T). Therefore, stud walls which are cut to exact length at the mill for modern construction are designated by letters P.E.T
Answer:
Δw =7.95 kg/1000m^3
q = 62362.3 kg/1000m^3
Explanation:
To solve this problem we first need to use the psycrometric chart to determine the enthalpy h1, specific volume vi and absolute humidity col by using the given temperature T1 = 32°C and the relative humidity Ф1 = 95%.
h_1 = 106.5 kJ/kg
v_1 = 0.91 m^3/kg
w_1 = 0.02905
We will also need the enthalpy h2 and the absolute humidity w_2 at the exit point. We will again use the pyscrometric chart and the given temperature T_2 = 24°C. From the problem we also know that the exit relative humidity is = 60%.
h2 = 52.6 kJ/kg
w_2 = 0.01119
We need to express the final results in units per 1000 m^3. To do that we will need the mass m of this volume of air V and to calculate that we will use the given pressure p = 1 atm = 101.3 kPa.
m = R_a*T_1/V.p
m = 1000*101.3/0.287*305K
m = 1157 kg
Because it is a closed system, the amount of water removed Δw can be calculated as:
Δw =w_1 - w_2
Δw =0.02905- 0.01119
Δw =0.00687 kg/kg* 1157kg/1000m^3
Δw =7.95 kg/1000m^3
From the energy balance equation we can calculate the specific heat q removed from the air.
q = h_1 - h_2
q = 106.5 kJ/kg - 52.6 kJ/kg
q = 53.9 kJ/kg * 1157kg/1000m^3
q = 62362.3 kg/1000m^3
MVC architecture is defined as the architectural design that is used by software engineers for programming languages.
<h3>What are the various models of MVC architecture?</h3>
The various types of MVC architecture include the following:
- The controller: This model is used to control logic and acts as the coordinator between the View and the Model.
- The view: It displays the information from the model to the user.
- The model: It is used to implement the domain logic.

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
B.)

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.
