ANS:C -
70° 30'
BB of line AB = 190-180 = 10.
BB of line CB = 360-260 30' = 100 30'.
= 100 30'+10 = 110 30'.
= 180-110 30' = 70 30'.
(190*-180*)+(270*-260*30')+90*.
=10*+9*30'+90*.
109*30'.
The included angle ABC is 260°30'-190°=70°30'00''.
As per your calculation, BB of line CB = 360-260 30' = 99 30' (check properly).
AB=270-190=80.
BC=270-260.30=10.30.
Then 80-10.30=70.30.

ANS:B - increases in winter
For the same process conditions, the reflux ratio of an unlagged distillation column increases in winter.
Here's why:
-
Temperature Difference: In winter, the external temperature is generally lower compared to summer. In an unlagged distillation column, the temperature difference between the external environment and the column affects the condensation rate and thus the reflux ratio.
-
Higher Condensation Rate in Winter: In colder temperatures, the condensation rate of the overhead vapor (reflux) is higher because the temperature difference between the vapor and the surrounding environment is greater. As a result, more vapor condenses back into liquid, leading to an increased reflux ratio.
-
Stability of Process Conditions: Assuming the process conditions remain constant, the increased reflux ratio in winter helps maintain stability and efficiency in the distillation column by providing more liquid reflux for better separation of components.
Therefore, the reflux ratio of an unlagged distillation column typically increases in winter due to the colder external temperatures, leading to higher condensation rates and a greater amount of liquid reflux.

ANS:C - both (a) and (b)
The behaviour of a mass of fluidised solid depends mainly on both (a) and (b): the fluid characteristics and the particle size.
Explanation:
-
Fluid Characteristics:
- The properties of the fluid, such as its velocity, density, and viscosity, are crucial in determining the fluidisation behaviour. The fluid must flow through the bed of particles at a sufficient velocity to lift and suspend the particles, creating a fluidised state.
-
Particle Size:
- The size and distribution of the solid particles significantly affect how they interact with the fluid and with each other. Smaller particles are easier to fluidise and tend to stay suspended with lower fluid velocities, whereas larger particles require higher velocities.
Both factors are interdependent and play critical roles in the fluidisation process. Therefore, the correct choice is both (a) and (b).
