last question:If the Good X falls by 20%, then, it will be Rs.2, and according to his demand 100 units will be equal to Rs.200.
cause if one unit=rs.2, then 100units=100×2=200.
Air enters a 28-cm diameter pipe steadily at 200 kPaand 208C with a velocity of 5 m/s. Air is heated as it flows, and leaves the pipe at 180 kPa and 408C. Determine (a) the volume flow rate of air at the inlet, (b) the mass flow rate of air, and(c) the velocity and volume flow rate at the exit.
Answers
Answer:
(a) [tex]\dot V_1[/tex] = 0.308 m³/s
(b) [tex]\dot m[/tex] = 0.732 kg/m³
(c) v₂ = 5.94 m/s.
Explanation:
(a) The volume flow rate is given by the cross sectional area of the pipe × Velocity of flow of air
Diameter of pipe = 28 cm = 0.28 m
The cross sectional area, A, of the pipe = 0.28²/4×π = 0.0616 m²
Volume flow rate = 5 × 0.0616 = 0.308 m³/s
[tex]\dot V_1[/tex] = 0.308 m³/s
(b) From the general gas equation, we have;
p₁v₁ = RT₁ which gives;
p₁/ρ₁ = RT₁
ρ₁ = p₁/(RT₁)
Where:
ρ₁ = Density of the air
p₁ = 200 kPa
T₁ = 20 C =
R = 0.287 kPa·m³/(kg·K)
ρ₁ = 200/(0.287 ×293.15) = 2.377 kg/m³
The mass flow rate = Volume flow rate × Density
The mass flow rate, [tex]\dot m[/tex] = 2.377×0.308 = 0.732 kg/m³
[tex]\dot m[/tex] = 0.732 kg/m³
(c) The density at exit, ρ₂, is found from the the universal gas equation as follows;
ρ₂ = p₂/(RT₂)
Where:
p₂ = Pressure at exit = 180 kPa
T₂ = Exit temperature = 40°C = 273.15 + 40 = 313.15 K
∴ ρ₂ = 180/(0.287×313.15) = 2.003 kg/m³
[tex]\dot m[/tex] = ρ₂×[tex]\dot V_2[/tex]
[tex]\dot V_2[/tex] = [tex]\dot m[/tex]/ρ₂ = 0.732/2.003 = 0.366 m³/s
[tex]\dot V_2[/tex] = v₂ × A
v₂ = [tex]\dot V_2[/tex]/A = 0.366/0.0616 = 5.94 m/s.
v₂ = 5.94 m/s.

Royce has a Bevel protractor with a damaged vernier scale. What limitation will Royce face if he uses this protractor to measure angles?
Answers
Answer:
Limitation in the level of possible accuracy of the that can be obtained to mainly whole degrees
Explanation:
The angle measurement values are located around the circularly shaped bevel protractor to which a Vernier scale can be attached to increase the accuracy of the angle measurement reading
The accuracy of the bevel protractor is up to 5 arc minutes or 1/12° with the space on the Vernier scale having graduations of 1/12°, such that two spaces on the main scale is 5 arc minutes more than a space on the Vernier scale and the dimensions of the coincidence of the two scale will have an accuracy of up to 1/12°
Therefore, whereby the Vernier scale is damaged, the accuracy will be limited to the accuracy main scale reading in whole degrees.

Mike has a factory that manufactures highly customized products. Which type of manufacturing system is most suitable for it?
Answers
Answer:
Custom Manufacturing System.
Explanation:
As per the custom manufacturing system, each object is made by a unit of a producer like a craftsman or a group who works entirely on the concerned product. This manufacturing system is characterized by the use of machines and they appear to be highly skilled in their tasks and can not generate more than one object at a time. This also appears to be correlated with both the highest quality goods and the lowest volume efficiency.

BHE:FLI:JPM next sequence
Answers
Answer:
NTQ
Explanation:
The given sequence is
BHE : FLI : JPM
If is clear that, alphabets on first places are B, F, J. Difference between their place vales is 4.
B+4=F,F+4=J ; so alphabet on first place of next term of sequence is J+4=N.
Similarly, alphabets on second places are H, L, P. Difference between their place vales is 4.
H+4=L,L+4=P ; so alphabet on second place of next term of sequence is P+4=T.
Alphabets on third places are E, I, M. Difference between their place vales is 4.
E+4=I,I+4=M ; so alphabet on third place of next term of sequence is M+4=Q.
Therefore, the next term is NTQ.

If both the low-side and the high-side pressures are low, which of these could be the cause?
A. High refrigerant charge
B. Defective cooling fan
C. Low refrigerant charge
D. TXV. stuck open
Answers
Answer:
The correct option is;
C. Low refrigerant charge
Explanation:
Where both the low-side and the high-side pressure are low the refrigerant is low which may be as a result of a leak
When there is a low refrigerant charge there will be a larger range over which to compress the refrigerant increasing the work required and thus the heat in the system and the due to insufficient refrigerant, the entire system is under served and the evaporator super-heats due to lack of refrigerant
The liquid-line, the TVX evaporator and compressor will see less fluid flow and hence lesser pressures on the low-side and high-side of the refrigeration system.
the ____ method is the safest turning technique to use as it does not expose your hands to the airbags deployment area
Answers
Answer:
Push/pull Method
Explanation:
Push/pull method is seen as the best method to use when a driver what to steer a wheel to point the car in a particular direction reason been that PUSH/PULL method enables the driver to sit perfectly well in order to firmly hold the wheel which is why this method is often recommended as the safest and most effective way of steering than other steering method.
Therefore the PUSH/PULL method is the safest and the best turning technique to use because it does not expose the driver hands to the airbags area reason been that air bag are sometimes place in the centre of the steering wheel which means that when a driver cross his/her arms when steering will block the air bag in a situation where the air bag needed to explode out because airbag can explodes out with a lot of force which in turn could force the driver arms towards his/ her face which is dangerous.

The gear lube level is being checked in a manual transmission. Technician A says it should run out when the plug is removed. Technician B says that some transmissions use motor oil as gear lube. Who is correct?
Answers
Answer:
Both technician A and B are correct
Explanation:
The function of the gear lube drain plug is to drain the automatic transmission fluid from the gear box
Although motor oil is for the engine, motor vehicle transmission uses different oil types as the transmission system or automatic transmission system (ATF) operates in an closed system environment it is free from fuel contamination that motor oil absorbs
As such depending on the specification, manual transmission oil can range from hypoid oil, motor oil or automatic transmission oil.

The structure of a house is such that it loses heat ata rate of 3800 kJ/h per8C difference between the indoors andoutdoors. A heat pump that requires a power input of 4 kWis used to maintain this house at 248C. Determine the lowestoutdoor temperature for which the heat pump can meet theheating requirements of this house.
Answers
Answer:
The lowest outdoor temperature for which the heat pump can meet the requirement of the house is -9.6°C
Explanation:
The coefficient of performance of a heat pump, COP, is given by the relation;
[tex]COP_{hp} = \dfrac{T_2}{T_2 - T_1} = \dfrac{Q_1\times (T_2 - T_1)}{\Sigma W}[/tex]
The rate of heat loss [tex]\dot Q_1[/tex] = 3800 kJ/h = 3800 ×1/60 × 1/60 kJ/s = 1.06 kJ/s
The power input = 4 kW = 4 kJ/s
The temperature indoors = 24 + 273.15 = 297.15 K
Therefore, we have;
[tex]COP_{hp} = \dfrac{297.15}{297.15- T_1} = \dfrac{1.06 \times (297.15- T_1)}{4}[/tex]
4×297.15= (297.15- T₁) × 1.06×(297.15- T₁)
Which gives;
18/19·T₁²-627.32·T₁+92014.97=0
(T₁ -263.59)·(T₁ - 330.71) = 0
The solutions are;
T₁ = 263.59 K or T₁ = 330.71 K
The lowest temperature = 263.59 K which is -9.6°C
The lowest temperature = -9.6°C.
