Answer:
The laminar flow is generally given in high viscosity fluids such as honey or oil, it has the characteristic of flowing in an orderly manner, the walls of the tube have a zero speed while in the center it has a maximum speed.
turbulent flow is characterized by fluid velocity vectors presenting themselves in a disorderly manner and in all directions.
I attached the drawings for the velocity profile in laminar and turbulent flow.
Answer:
Chord ratio:
It is the ratio of thickness to the chord.It is also knows as thickness ratio.
Chord ratio measure the performance of wing when it is operating at the transonic speed.
When the speed cross the speed of sound wave then that wave creates the shock wave and these shock leads to produce drag force on the aerofoil profile.When Mach number is one then it means that if Mach increase then it will leads increase then drag force.
Answer:
as pull up network. the metteing point of pull down and pull up is the point where we take the output
note 1: if two n-mos are connected in series it gives logical AND and p-mos paralle gives logical-AND
note 2: if two n-mos are connected in parallel it gives logical OR and p-mos series gives logical-OR
note 3: output is always complement of what we implement
example Y= (AB)'
image attached
A) F = (ABC + D(A+B) )'
pulldown:
this can be realize by takeing three n-mos in series which gives ABC ,two n-mos are parallel which in series with another n-mos whic gives D(A+B), now connect ABC and D(A+B) in parallel
pull up
this can be realize by takeing three p-mos in parallel which gives ABC ,two p-mos are series which is in serires with
another p-mos whic gives D(A+B), now connect ABC and D(A+B) in series
the out put will be (ABC + D(A+B) )'
so we require total 6-mos and 6-pmos total 12mos transistors
B) F = AC + BD
pull down
this can be realize by takeing two n-mos in series which gives AB ,two n-mos are in series
which whic gives BD, now connect AC and BD in parallel
pull up
this can be realize by takeing two p-mos in parallel which gives Ac ,two p-mos are in parallel
which whic gives BD, now connect AC and BD in series
the output is (AC+BD)'
to avoid the complement we have to connect the output to c-mos inverter then we get AC+BD
so we require 5-nmos, 5-pmos total 10 mos transistors
Answer:
The three phase full load secondary amperage is 2775.7 A
Explanation:
Following data is given,
S = Apparent Power = 1000 kVA
No. of phases = 3
Secondary Voltage: 208 V/120 V <em>(Here 208 V is three phase voltage and 120 V is single phase voltage) </em>
<em>Since,</em>

<em /><em />
The formula for apparent power in three phase system is given as:
Where:
S = Apparent Power
V = Line Voltage
I = Line Current
In order to calculate the Current on Secondary Side, substituting values in above formula,
