ANS:A -

Arc = φ *R......... φ in rad.
φ rad = Arc/R.
φ = Arc/(R*rad) = x/(R*206265). x = Angular value of one graduation of tube of length.
φ = Second.
R = Radius.

D = 206265 sec.
(x/r)*d = (x/r)*206265.

φ = x/206265. Yeah,angle= (arc/radius) radians.
= (d/r) * 206265 sec.
= (206265d/r).
(1rad=206265sec).

ANS:C - both 'a' & 'b'.

The correct answer is: both 'a' & 'b'. Pressure gauges are not directly connected to live steam lines due to several reasons:

1. Avoiding overheating: By interposing a loop or syphon close to the pressure gauge, the temperature of the medium reaching the gauge is reduced. This helps in preventing overheating of the tubes and bellows which operate the gauge, minimizing errors and potential damage due to excessive heat.
2. Forming a seal of water by steam condensate: The loop or syphon allows for the condensation of steam into water. This water forms a seal that fills the tube or bellows at the pressure being measured. This helps in accurately transmitting the pressure to the gauge while preventing the direct contact of high-temperature steam with the sensitive components of the gauge.

ANS:A - non-steady uniform

Gradually varying fluid flow typically falls under the category of non-steady non-uniform flow. Here’s an explanation of each type of flow:

1. Steady Uniform Flow: This type of flow has constant velocity magnitude and direction at any given point in the flow field and does not change over time. The flow properties are uniform throughout the domain.
2. Steady Non-uniform Flow: In steady non-uniform flow, the velocity magnitude and/or direction vary at different points in the flow field, but these variations do not change with time.
3. Non-steady Uniform Flow: This refers to flow where the velocity magnitude and direction are uniform initially but change with time, becoming non-uniform over time.
4. Non-steady Non-uniform Flow: This type of flow involves variations in velocity magnitude and direction both spatially and temporally. The flow properties change both with respect to location in the flow field and over time.

ANS:B - Odisha

Odisha women's team has won its first-ever gold in Senior Nationals the final of the 12th Hockey India Senior Women's National Championship.

ANS:B - Shompen Tribes

The Shompen Tribes from Great Nicobar Island participated in voting for the first time. As a Particularly Vulnerable Tribal Group (PVTG), they reside in dense tropical rainforests and belong to the Mongoloid group. Their participation in the electoral process marks a significant step in their engagement with mainstream society, highlighting efforts towards inclusion and empowerment of tribal communities.

ANS:B - Kerala

Kerala Chief Minister Pinarayi Vijayan has inaugurated a project of the Women and Child Development department to provide milk and eggs to children at all Anganwadis in the state.

ANS:B - 1973

The Chipko Movement, a significant environmental movement, started in Uttarakhand in 1973. It was a response to rampant deforestation and commercial activities threatening the region's forests. The movement gained attention for its non-violent methods, including tree-hugging, to protect natural resources and raise awareness about ecological conservation.
