The most economical range of absorption factor typically depends on the specific application and process conditions. However, in many industrial applications, the absorption factor (also known as the liquid-to-gas ratio or the solvent-to-feed ratio) is often in the range of 5 to 15. In absorption processes, such as gas absorption or liquid extraction, the absorption factor represents the ratio of the solvent flow rate to the feed flow rate. This ratio affects the efficiency and cost of the process. A higher absorption factor generally indicates a larger amount of solvent relative to the feed, which can enhance the mass transfer efficiency and improve the separation performance. However, excessively high absorption factors can lead to higher solvent usage and increased operating costs. On the other hand, too low absorption factors may result in inefficient mass transfer and lower separation efficiency. Therefore, an optimal range of absorption factor is often chosen to balance the trade-offs between efficiency and cost-effectiveness for a specific application. While the range of 5 to 15 is commonly considered economical for many industrial absorption processes, the optimal range may vary depending on factors such as the properties of the feed and solvent, the desired separation efficiency, and the economics of the process.

ANS:D - all (a), (b) & (c).

The transition from laminar flow to turbulent flow can be influenced by several factors, and the statement "all (a), (b) & (c)" is accurate. Let's break down each factor:

1. Surface Roughness and Curvature:
   • Surface roughness and irregularities on the walls of the pipe or channel can disturb the smooth flow of fluid, causing small disturbances or eddies to form. These disturbances can promote the transition from laminar to turbulent flow by initiating the breakup of laminar boundary layers.
2. Vibration:
   • Vibration or oscillations in the fluid or the container carrying the fluid can introduce disturbances that disrupt laminar flow patterns. These disturbances can trigger the transition to turbulent flow by causing flow instabilities.
3. Pressure Gradient and Compressibility:
   • An increase in the pressure gradient (pressure drop) along the flow direction can lead to higher flow velocities. This higher velocity can exceed the critical Reynolds number, initiating turbulent flow.
   • Compressibility effects can also influence the transition to turbulent flow, especially in gases where changes in density due to pressure changes can affect flow stability.

Conclusion:

ANS:D - Kerala

The "Constitutional Literacy Campaign" was launched in Kerala.

ANS:B - Arunachal Pradesh

The 9th edition of the Pakke Paga Hornbill Festival (PPHF) is set to take place at Seijosa in the Pakke Kessang district of Arunachal Pradesh from January 18-20, 2024. Initiated in 2015, the festival aims to celebrate the Nyishi tribal group's significant role in conserving hornbills within the Pakke Tiger Reserve (PTR). The event focuses on recognizing the Nyishi tribe's contributions to hornbill conservation, generating alternative sources of income for the region, and raising awareness about PTR and its wonders across India.

ANS:B - Uttarakhand

The 'Soul of Steel' challenge was launched in Uttarakhand.

ANS:D - Tamil Nadu

Tamil Nadu, known for its cultural richness, initiated the Jallikattu competition in the village of Avaniyapuram, marking a significant highlight of the Pongal harvest festival celebrated in the second week of January. The three-day event, with Avaniyapuram hosting the first day, Palamedu on the second day, and Alanganallur on the third, showcases the traditional bull-taming sport's excitement.
