meaning of construction

Answer:

The powertrain system is one of the major systems on the vehicle.

Tech B states that this system usually contains the engine and transmission.

Technician B is correct.

Explanation:

The powertrain system contains three interconnected systems: the engine, the transmission, and the drivetrain.  The engine part is the power source of the powertrain that ensures vehicular movement.  The transmission system converts the engine's power into the normal movement of the vehicle.  The drivetrain consists of the transmission, driveshafts, and the axles.  These three parts of the powertrain system work seamlessly to ensure that the vehicle is able to move with some speed back and front, as may be desired.

Answer:

Two technicians are discussing HD-OBD for trucks

Technician a says that the simplest most familiar definition is the diagnostic function of electronic control system to identify or self-diagnose system fault and report fault codes.

Technician A is correct.

Explanation:

Onboard Diagnostics (OBD) is a vehicle's self-diagnostic tool which enables technicians to access the diagnostic information for the purpose of performance monitoring and analyzing repair needs of vehicles.  OBD2 is the diagnostic system that is included in every vehicle made after 1996.  The diagnostics can check the engine and other vehicle systems and also communicate possible vehicular glitches that happen.

The initial enthalpy and the entropy of the saturated water can be found out from the table of A-12E

i.e.   [tex]$h_1= 101 \ \text{Btu/lbm}$[/tex]

       [tex]$s_1 = 0.22717 \text{ Btu/lbmR}$[/tex]

Since the process mentioned above is an adiabatic compression process, the entropy will remain constant throughout the process. Therefore, we take the value of entropy and the final pressure using the table with few interpolations and also approximations to find the final enthalpy. It is given by :

       [tex]$h_2= 116.09 \text{ Btu/lbm}$[/tex]

So the work input from the energy balance equation :

       [tex]$\dot{W} + \dot{m}h_1 = \dot{m}h_2$[/tex]

          [tex]$w=h_2 - h_1$[/tex]

              = 116.09 - 101

              = 15.09

Therefore, [tex]$w= 15.09 \text{ Btu/lbm}$[/tex]

Answer:

Explanation:

Given;

current at resonance, I = 0.2 mA

applied voltage, V = 250 mV

resonance frequency, f₀ = 100 kHz

capacitance of the circuit, C = 0.04 μF

At resonance, capacitive reactance ([tex]X_c[/tex]) is equal to inductive reactance ([tex]X_l[/tex]),

[tex]Z = \sqrt{R^2 + (X_ l - X_c)^2} \\\\But \ X_l= X_c\\\\Z = R[/tex]

Where;

R is the resistance of the circuit, calculated as;

[tex]R = \frac{V}{I} \\\\R = \frac{250 \ \times \ 10^{-3}}{0.2 \ \times \ 10^{-3}} \\\\R = 1250 \ ohms[/tex]

The inductive reactance is calculated as;

[tex]X_l = X_c = \frac{1}{\omega C} = \frac{1}{2\pi f_o C} = \frac{1}{2\pi (100\times 10^3)(0.04\times 10^{-6} ) } = 39.789 \ ohms\\[/tex]

The inductance is calculated as;

[tex]X_l = \omega L = 2\pi f_o L\\\\L = \frac{X_l}{2\pi f_o}\\\\L = \frac{39.789}{2\pi (100 \times 10^3)} \\\\L= 6.3 \ \times \ 10^{-5} \ H\\\\L = 0.063 \times \ 10^{-3} \ H\\\\L = 0.063 \ mH[/tex]

Answer: the drawdown of the lake in centimeters is 3.02 cm

Explanation:

Given data;

Power of motor = 1000 W

efficiency M = 50% = 0.5

so Effective power = 1000 × 0.5 = 500 W

time t = 2 hrs = 2 × 60 × 60 = 7200 secs

so

Energy = p × t = 500 × 7200 = 3,600,000 J

Now Energy required to pump water to height h = mgh (J)

3,600,000 J = mgh

m = 3,600,000 / gh

given that; h is 2.43 and we know that g is 9.81, we substitute

m = 3,600,000 / (9.81 × 2.43)

m = 3,600,000 / 23.8383

m = 151017.48 kg

Now we know that, Volume = Mass / Density          [density of water]

so, Volume = 151017.48  / 1000

Volume = 151.01748 kg/m³

given that surface area = 5000 m²

Drawdown = 151.01748 / 5000

Drawdown = 0.3020 m

we convert to centimeter

Drawdown = 0.3020 m × 100

Drawdown = 3.02 cm

Therefore the drawdown of the lake in centimeters is 3.02 cm

Answer:

a = 40

b = 29

Explanation:

Give a place holder for the numbers that we don't know.

Lets call the two numbers a and b.

From the given info, we can write an expression and solve it:

"one number is 11 more than another number"

a = 11 + b

from this, we know that a > b.

''three times the larger number exceeds four times the smaller number by 4"

3a = 4b + 4

Now we have 2 equations, we can use them to solve using whatever method you want.

a = 11 + b

3a = 4b + 4

I will be using matrices RREF to solve for this.

a - b = 11

3a - 4b = 4

[tex]\begin{bmatrix}1 & -1 & 11\\3 & -4 & 4 \end{bmatrix}[/tex]

Answer:

the normal component of force F_n is F((√(r²-s²)) / r)

the tangential component of force F_t is F(s/r)

Explanation:

Given the data in the image;

from the free body diagram, we write the expression for ∅

sin∅ = s/r

cos∅ = (√(r²-s²)) / r

now expression for normal component of force is;

F_n = Fcos∅

we substitute

F_n = F((√(r²-s²)) / r)

Therefore, the normal component of force F_n is F((√(r²-s²)) / r)

Also for force F_t

F_t = Fsin∅

we substitute

F_t = F(s/r)

Therefore, the tangential component of force F_t is F(s/r)

Answer:

Hp = 23.86 m

Hence, 23.86 m head pump is required for this flow.

Explanation:

Solution:

Data Given:

Elevation = Z = 14.9 m

Friction of the ductile iron pipe = f = 0.019

Length of the ductile iron pipe connecting the reservoirs = 22.4 m

Diameter of the Pipe = D = 0.5 cm

Radius of the Pipe = r = D/2 = 0.25 cm

Performance Curve of the Pump = Hp = 23.9 - 7.59[tex]Q^{2}[/tex] , where Hp is in meters.

[tex]Q^{}[/tex] is in Liters/second and equation is valid for 1.5 L/s

We are asked to find out the pump head required for this flow.

We need to apply the energy equation for this problem:

Energy Equation:

[tex]\frac{P1}{\beta 1} + \frac{v1^{2} }{2g} + Z1 + Hp = \frac{P2}{\beta 2} + \frac{v2^{2} }{2g} + Z2 + H_{L}[/tex]

where, [tex]\beta[/tex] = specific weight of the fluid.  

v1 = 0

P1 = P2 = P

Z1 = 0

Z2 = 14.9

Hence,

New equation is:

[tex]Hp = \frac{v2^{2} }{2g} + Z2 + H_{L}[/tex]

And

[tex]H_{L}[/tex] = [tex]\frac{fLv^{2} }{2gD}[/tex]

So,

[tex]Hp = \frac{v2^{2} }{2g} + Z2 + \frac{fLv^{2} }{2gD}[/tex]

Now, converting formula of v into terms of Q, we get

Hp = 23.9 - 7.59[tex]Q^{2}[/tex]

[tex]Hp = \frac{Q2^{2} }{2(9.81)(\frac{\pi }{4}(0.05^{2}))^{2} } + 14.9 + \frac{(0.09)(22.4)Q^{2} }{12.1(0.05)^{2} }[/tex]

23.9 - 7.59[tex]Q^{2}[/tex] = [tex]\frac{Q2^{2} }{2(9.81)(\frac{\pi }{4}(0.05^{2}))^{2} } + 14.9 + \frac{(0.09)(22.4)Q^{2} }{12.1(0.05)^{2} }[/tex]

Solving for Q, we will get

9 - 7.59[tex]Q^{2}[/tex] = 13233.71[tex]Q^{2}[/tex] + 112555.37[tex]Q^{2}[/tex]

[tex]Q^{}[/tex] = 7.154 x [tex]10^{-5}[/tex] [tex]m^{3}/s[/tex]

Converting it into L/s

Q = 0.0715 L/s

Putting this value of Q into the Hp equation to get the required answer:

Hp = 23.9 - 7.59[tex]Q^{2}[/tex]

Hp = 23.9 - 7.59 x [tex]0.0715^{2}[/tex]

Hp = Pump head

Hp = 23.86 m

Hence, 23.86 m head pump is required for this flow.
