Answer:
B. Information processing and decision-making
Explanation:
Technician A says that a circuit with continuity reads 0 ohms. Technician B says that an open circuit reads 0 ohms. Who is correct
Answer:
A
Explanation:
An open circuit has infinite resistance, not 0. A circuit with continuity usually measures a few ohms or less, depending on the length and gauge of the wire and the condition of the connections. Often, on a general-purpose ohmmeter, the reading is very near 0 ohms.
Technician A is correct.
Refrigerant-134a at 1 MPa and 100 C is to be cooled to 1 MPa and 28 C in a condenser by air. The air enters at 125 kPa and 25 C with a mass flow rate of 697 kg/min and leaves at 97 kPa and 58 C. Determine the mass flow rate of the refrigerant. Assume air has a constant heat capacity determined at room temperature. Report the mass flow rate of the refrigerant in kg/min with one decimal digit, for example 95.3 or 105.6.

A rope is wrapped three and a half times around a cylinder. Determine the range of force T exerted on
the free end of the rope for maintaining equilibrium that is required to just support a 5 kN weight. The
coefficient of friction between the rope and the cylinder is 0.2
The range of force exerted at the end of the rope is; 285.7 N to 1,000 N.
What is the Net horizontal force?The net horizontal force of the cylinder when it is at equilibrium position can be found by applying Newton's second law of motion. Thus;
∑F = 0
F - μF_n = 0
We are given;
F_n = 5 kN = 5000 N
μ = 0.2
Thus;
F - 0.2(5,000) = 0
F - 1,000 = 0
F = 1,000 N
The strength of the applied force will be increasing as the number of turns of the rope increases. Thus;
Minimum force = Total force/number of turns of rope
Since rope is wrapped three and half times, then;
number of turns = 3.5
Thus;
minimum force = 1,000/3.5
minimum force = 285.7 N
Thus, the range of force exerted at the end of the rope is 285.7 N to 1,000 N.

From the top of a vertical cliff 80m high, the angles of depression of 2 buoys lying due west of the cliff are 23° and 15° respectively. How far are the buoys apart?
Answer:
110 m
Explanation:
The geometry of the problem can be modeled by a right triangle. The height of the cliff forms one leg, and the distance to a buoy forms the other leg. The angle of depression is opposite the height of the cliff. An appropriate trig relation is ...
Tan = Opposite/Adjacent
Solving for the Adjacent side (the distance to the buoy), we find ...
Adjacent = Opposite/Tan
distance to buoy 1 = (80 m)/tan(23°) ≈ 188.468 m
distance to buoy 2 = (80 m)/tan(15°) ≈ 298.564 m
Then the distance between the buoys is ...
298.564 -188.468 m ≈ 110 m
The buoys are about 110 meters apart.

A completely reversible heat engine operates with a source at 1500 R and a sink at 560 R. At what rate must heat be supplied to this engine, in Btu/h, for it to produce 5 hp of power?
Answer: iy had around 5000 R
Explanation:
a. An 80-percent efficient pump with a power input of 20 hp is pumping water from a lake to a nearby pool at ar ate of 1.5 ft3 /s through a constant-diameter pipe. The free surface of the pool is 80 ft above that of the lake. Determine the mechanical power used to overcome frictional effects in piping.
b. Water is pumped from a lake to a storage tank 15 m above at a rate of 70 L/s while consuming 15.4 kW of electric power. Disregarding any frictional losses in the pipes and any changes in kinetic energy. Determine:
1. The overall efficiency of the pump–motor unit.
b. The pressure difference between the inlet and the exit of the pump.
Answer:
A) mechanical power used to overcome frictional effects in piping = 2.373 HP
B) efficiency = 66.82%
Pressure difference = 147 KPa
Explanation:
We are given;
efficiency of pump; η = 80% = 0.8
power input of pump;P_pump,in = 20 hp
rate being pumped; Q = 1.5 ft³/s = 0.04248 m³/s
free surface of pool; Δz = 80 ft = 24.384 m
mechanical pumping power used to deliver water is;
W_u = η × P_pump,in
W_u = 0.8 × 20
W_u = 16 Hp
Now, change in total mechanical energy of water will be equal to the change in potential energy.
Thus, it is expressed as;
ΔE_mech = ρ × Q × g × Δz
Where ρ is density of water = 1000 kg/m³
Thus;
ΔE_mech = 1000 × 0.04248 × 9.81 × 24.384 = 10,161.5150592 J/s
Converting to HP gives;
ΔE_mech = 13.627 HP
Now, mechanical power used to overcome frictional effects is given by;
W_frict = W_u - ΔE_mech
W_frict = 16 - 13.627
W_frict = 2.373 HP
B) We are now given;
W_elect,in = 15.4 KW
Volumetric flow rate; q = 70 l/s = 0.07 m³/s
Height; h = 15 m
Mass flow rate; m' = qρ
Where ρ is density of water = 1000 kg/m³.
m' = 0.07 × 1000
m' = 70 kg/s
Now,
ΔE_mech = workdone through height of 15m
Thus;
ΔE_mech = m'gh
ΔE_mech = 70 × 9.8 × 15
ΔE_mech = 10,290 W = 10.29 Kw
efficiency of the pump–motor unit = ΔE_mech/(W_elect,in) = 10.29/15.4 = 0.6682 or 66.82%
Pressure difference = ρgh = 1000 × 9.8 × 15 = 147,000 Pa = 147 KPa

Given a series silicon diode circuit with the resistor R=2 ko ohms and an applied voltage of 10
V, what is Ipg?
A) 0.5 mA
B) 10 mA
C) 4.65 mA
D) 1.0 mA
Answer:
C) 4.65 mA
Explanation:
The series circuit will have a voltage drop of about 0.7 V across the silicon diode, so the voltage drop across the 2 kΩ resistor is 10 -0.7 = 9.3 V. The current through the resistor is given by Ohm's Law:
I = V/R = 9.3 V/(2 kΩ)
I = 4.65 mA

(TCO 6) A cable company is running a fiber-optic link between the head end and a neighborhood five miles away. The signal applied to the fiber goes through an optical connector having 3dB LOSS at the head end, the fiber has a LOSS of 1 dB, and the connector at the end of the fiber has a LOSS of 3 dB before being applied to an amplifier used to make up for the losses. The desired signal at the output of the amplifier is 10 dBm, and the signal level applied to the fiber connector at the head end is 10 dBm. What should the gain of the amplifier be to have 10 dBm at the output of the neighborhood amplifier
Answer:
7 dB
Explanation:
The total loss from the headend to the amplifier input is the sum of the losses along the fiber, that we simply add as they are in dBs:Total Loss = 3 dB + 1 dB + 3 dB = 7 dBThe signal at the amplifier input is just +10 dBm- 7 dB = +3 dBmSo as the output level at the Headend and the one at the output of the neighborhood amplifier must be equal each other (compensating all losses in the path), the amplifier gain must be equal to the cumulative loss, i.e. , 7 dB, so that the amplifier output level be + 10 dBm.explain wet and dry compression tests

Answer:
0.42 kg
Explanation:
Heat is proportional to mass by way of the conversion factor that is the inverse of the specific heat.
[tex]\dfrac{63000\text{ J}}{\dfrac{3000\text{ J}}{\text{kg$\cdot$K}}\cdot(65-15)\text{ K}}=0.42\text{ kg}[/tex]
The mass of the liquid is about 0.42 kg.
An experimental arrangement for measuring the thermal conductivity of solid materials involves the use of two long rods that are equivalent in every respect, except that one is fabricated from a standard material of known thermal conductivity kA while the other is fabricated from the material whose thermal conductivity kB is desired. Both rods are attached at one end to a heat source of fixed temperature Tb, are exposed to a fluid of temperature [infinity] T[infinity], and are instrumented with thermocouples to measure the temperature at a fixed distance x1 from the heat source. If the standard material is aluminum, with kA= 200 W/m·K, and measurements reveal values of TA= 75°C and TB= 70°C at x1 for Tb= 100°C and [infinity] T[infinity]= 25°C, what is the thermal conductivity kB of the test material?
Answer: the thermal conductivity of the second material is 125.9 W/m.k
Explanation:
Given that;
The two rods could be approximated as a fins of infinite length.
TA = 75°C, θA = (TA - T∞) = 75 - 25 = 50°C
TB = 70°C θB = (TB - T∞) = 70 - 25 = 45°C
Tb = 100°C θb = (Tb - T∞) = (100 - 25) = 75°C
T∞ = 25°C
KA = 200 W/m · K , KB = ?
Now
The temperature distribution for the infinite fins are given by
θ/θb = e^(-mx)
θA/θb= e^-√(hp/A.kA) x 1 --------------1
θB/θb = e^-√(hp/A.kB) x 1---------------2
next we take the natural logof both sides,
ln(θA/θb) = -√(hp/A.kA) x 1 ------------3
In(θB/θb) = -√(hp/A.kB) x 1 ------------4
now we divide 3 by 4
[ ln(θA/θb) /in(θB/θb)] = √(KB/KA)
we substitute
[ In(50/75) /In(45/75)] = √(KB/200)
In(0.6666) / In(0.6) = √KB / √200
-0.4055/-0.5108 = √KB / √200
0.7938 = √KB / 14.14
√KB = 11.22
KB = 125.9 W/m.k
So the thermal conductivity of the second material is 125.9 W/m.k
