ANS:C - Diameter of randomly packed tower is normally more than 1.2 metres.

The wrong statement is: "Diameter of randomly packed tower is normally more than 1.2 meters." In reality, the diameter of randomly packed towers can vary widely depending on the specific application and requirements. While some packed towers may indeed have diameters larger than 1.2 meters, many others can have smaller diameters, especially in situations where space is limited or where smaller-scale operations are preferred. Therefore, the statement that the diameter of randomly packed towers is normally more than 1.2 meters is not universally accurate.

ANS:B - first power of the roughness.

The losses in open channel flow generally vary as the first power of the roughness.

Explanation:

1. Open Channel Flow:
   • Open channel flow occurs when a fluid flows in a conduit with a free surface exposed to atmospheric pressure, such as rivers, streams, and canals.
2. Losses in Open Channel Flow:
   • Losses in open channel flow are primarily due to friction between the moving fluid and the channel bed and walls, as well as other factors like bends, expansions, contractions, and transitions.
   • The magnitude of these losses depends significantly on the roughness of the channel bed and walls.
3. Variation with Roughness:
   • Empirical studies and equations (such as Manning's formula for uniform flow) show that the losses in open channel flow vary approximately as the first power (linearly) of the roughness height or roughness coefficient nnn.
   • Roughness directly affects the frictional resistance encountered by the flowing fluid, influencing the overall energy losses in the system.
4. Other Options:
   • Inverse of the roughness: This is not generally true; losses do not vary inversely with roughness.
   • Square of the velocity: This relates to kinetic energy and is not directly related to losses due to roughness.
   • Inverse square of hydraulic radius: This describes the resistance coefficient in Manning's equation, but not the variation of losses with roughness.

ANS:A - Istanbul, Turkey

The 19th Heads of Asian Coast Guard Agencies Meeting (HACGAM) took place in Istanbul, Turkey, from September 5th to September 8th, 2023. The Indian Coast Guard was represented by a four-member delegation led by DG Rakesh Pal, Director General Indian Coast Guard.

ANS:D - India

The world's highest fighter airfield will be constructed in Ladakh, India. The Border Roads Organisation (BRO) has initiated the construction of the airfield in Nyoma, which is located at an altitude of 13,700 feet. The airfield is expected to be completed by 2024 and will be able to accommodate fighter jets such as the Sukhoi Su-30MKI.

ANS:C - Bengaluru

The country’s first underground power transformer was installed in Bengaluru, Karnataka. The transformer was inaugurated by Energy Minister KJ George in a groundbreaking ceremony. The transformer is located at 15th Avenue in Malleswaram, Bengaluru. The installation of the underground power transformer is a significant step towards modernizing Bengaluru’s power distribution infrastructure.

ANS:C - Eastern Ladakh

The airfield will be constructed in the strategic Nyoma belt of eastern Ladakh. The Nyoma belt is located in the eastern Ladakh region, close to the Line of Actual Control (LAC) with China. The region is strategically important and the airfield will be a major asset for the Indian Armed Forces.
