ANS:B - 30°

Well conditioned triangle:all angles >30 & <120.
Ill conditioned triangle: any one angle <30 or >120.
Best conditioned triangle: an isosceles triangle with 2 angles 56.14' A triangle is said to be well-conditioned when its an angle between 30° and 120°. A well conditioned triangle has angle not less than 30 and not more than 120 respectively. In well condition triangles between 30and 120.
Less than 30.
More than 120. A well conditioned triangle mainly consists of nearly equilateral triangle, saying more precisely angles should lie between 30 and 120 degrees. A well conditioned triangle has angles not less than and more than respectively 90 and 120 degrees. A well conditioned triangle should have the following condition ie it should not be less than 20 degrees and not more than 130 degrees.

ANS:A - the water entrained by the circulating air.

The water entrained by the circulating air in a cooling tower refers to the process by which small droplets of water are carried away by the air as it passes through the tower. This phenomenon occurs due to the interaction between the air and the water within the cooling tower. In a cooling tower, warm water from an industrial process is circulated through the tower and distributed over a fill material, which increases the contact surface area between the water and the air. As the warm water flows over the fill material, it is exposed to a flow of air that is usually induced by fans at the base or top of the tower. The air, being cooler than the water, causes some of the water to evaporate into the air stream. This evaporation process helps to remove heat from the water, cooling it down. However, along with the evaporated water vapor, small droplets of liquid water are also entrained by the air stream as it passes through the tower. These entrained water droplets become part of the exhaust air leaving the cooling tower. While the majority of the water droplets are collected and returned to the cooling system, a fraction of them, known as drift, may escape the tower and be lost to the environment. Controlling drift is important in cooling tower operation to minimize water loss and potential environmental impact. Various methods such as the use of drift eliminators and proper tower design can help reduce the amount of water entrained by the circulating air.

ANS:A - Newtonion

A fluid which has a linear relationship between the magnitude of applied shear stress and the resulting rate of deformation is called a Newtonian fluid. Here's why:

• Newtonian Fluid: A Newtonian fluid is defined by Newton's law of viscosity, which states that the shear stress (τ\tauτ) between adjacent fluid layers is directly proportional to the velocity gradient (dudy\frac{du}{dy}dydu​). Mathematically, this relationship is expressed as: τ=μdudy\tau = \mu \frac{du}{dy}τ=μdydu​ where μ\muμ is the dynamic viscosity of the fluid.
• Linear Relationship: In a Newtonian fluid, the rate of deformation (velocity gradient) is directly proportional to the applied shear stress. This linear relationship holds true across a wide range of shear rates and stresses for Newtonian fluids.

ANS:A - Bangalore

Prime Minister Narendra Modi flagged off South India's first Vande Bharat Express train from KSR Bangalore city railway station. The train departed for Chennai Central amid loud cheers.

ANS:D - Ministry of Housing and Urban Affairs

Union Housing and Urban Affairs Minister Hardeep Singh Puri virtually launched the Transport 4 All Challenge Stage-2 and Citizen Perception Survey 2022.

ANS:C - tallow

The fatty material used in soap making is tallow. Tallow is a fatty material used in soap making, derived primarily from the fat of cattle or sheep. Here’s a detailed explanation:

What is Tallow?

• Source: Tallow is obtained from rendering animal fats, specifically from the abdominal area of animals like cows (beef tallow) and sheep (mutton tallow).
• Composition: It consists mainly of triglycerides, which are esters formed from glycerol and fatty acids. Tallow contains a mix of saturated and unsaturated fatty acids.

Role in Soap Making:

1. Saponification: In soap production, tallow undergoes a chemical reaction called saponification, where it reacts with an alkali (usually sodium hydroxide) to produce soap and glycerin. The fatty acids from tallow are key to this process.
2. Properties of Soap: Soaps made from tallow tend to be hard and have a stable lather. The saturated fatty acids contribute to the firmness, while unsaturated fatty acids enhance solubility.

Advantages of Using Tallow:

• Availability: Tallow is readily available and often used in traditional soap-making processes.
• Mildness: Soaps made from tallow are generally mild on the skin, making them suitable for personal care products.
• Stability: Tallow-based soaps have good shelf stability and are less prone to rancidity compared to those made from liquid oils.
