रेखा x = −2 में बिंदु (−4, 3) का प्रतिबिंब क्या होगा?
  • a)
    (−4, −7)
  • b)
    (4, 3)
  • c)
    (0, 3)
  • d)
    (−4, 7)
Correct answer is option 'C'. Can you explain this answer?

Wizius Careers answered
बिंदु के निर्देशांक (−4, 3) हैं।
चूंकि, हमें x = −2 के साथ परावर्तन (reflection) ढूंढना है, इसलिए y-निर्देशांक अप्रभावित रहता है।
अब, परावर्तन के लिए, परावर्तन रेखा से वस्तु तक की दूरी चित्र बिंदु तक की दूरी के बराबर होनी चाहिए।
तो, x-निर्देशांक के लिए:
यदि चित्र से परावर्तन रेखा तक की दूरी 'A' है और वस्तु से परावर्तन रेखा तक की दूरी 'B' है।
और, X1 बिंदु (−4, 3) का x निर्देशांक है।

इसलिए, सही उत्तर (0, 3) है।

Water at 10°C flows from a large reservoir to a smaller one through a 5-cm-diameter cast iron piping system, as shown in Fig. Determine the elevation z1 (in m) for a flow rate of 6 L/s.
The density and dynamic viscosity of water at 10° C are ρ = 999.7 kg⁄m3 and μ = 1.307 × 10−3 kg⁄m ∙ s. The coefficient of friction = 0.0315.
Correct answer is 'Range: 31 to 33'. Can you explain this answer?

Engineers Adda answered
The density and dynamic viscosity of water at 10° C are ρ = 999.7 kg⁄m3 and μ = 1.307 × 10−3 kg⁄m ∙ s.
The piping system involves 89 m of piping, a sharp-edged entrance (KL = 0.5), two standard flanged elbows (KL = 0.3 each), a fully open gate valve (KL = 0.2), and a submerged exit (KL = 1.06). We choose points 1 and 2 at the free surfaces of the two reservoirs. Noting that the fluid at both points is open to the atmosphere (and thus p1 = p2 = patm ) and that the fluid velocities at both points are zero (V1 = V2 = 0), the energy equation for a control volume between these two points simplifies to
Since the diameter of the piping system is constant. The average velocity in the pipe and the Reynolds number are
Therefore, the free surface of the first reservoir must be 31.9 m above the ground level to ensure water flow between the two reservoirs at the specified rate.

Simran Dasgupta answered  •  May 06, 2024
Definition of Aquicluded Formation:
An aquicluded formation is a geological formation that may contain water but does not allow the water to flow through it in significant amounts due to its low permeability. This means that while water may be present in the formation, it is unable to be extracted or yield water in usable quantities.

Characteristics of Aquicluded Formatio
... more
- Aquicluded formations have very low permeability, which means that water cannot flow through them easily.
- These formations act as barriers to the movement of water, preventing it from being extracted or accessed.
- Aquicluded formations are typically composed of impermeable materials such as clay or dense rock, which restrict the flow of water.

Difference Between Aquicluded and Aquifer Formations:
- Aquifers are geological formations that can store and transmit water in usable quantities, while aquicluded formations do not yield water.
- Aquifers have high permeability and allow water to flow through them easily, making them suitable for water extraction.
- Aquicluded formations, on the other hand, have low permeability and act as barriers to water flow.

Importance in Hydrogeology:
- Understanding aquicluded formations is important in hydrogeology as it helps in identifying and characterizing different types of geological formations.
- Aquicluded formations play a role in groundwater flow and storage, affecting the availability and accessibility of water resources.
- By studying aquicluded formations, hydrogeologists can better manage and protect groundwater sources for various uses.
