ANS:D - simple
Components with widely different boiling points in a binary mixture can be separated using simple distillation.
Here's why:
-
Principle: Simple distillation is a basic separation technique used to separate components of a mixture based on differences in their boiling points. When the boiling points of the components are significantly different, simple distillation can effectively separate them.
-
Process: In simple distillation, the mixture is heated to its boiling point, causing the component with the lower boiling point to vaporize first. The vapor is then condensed back into liquid form and collected separately from the component with the higher boiling point, which remains in the boiling flask.
-
Effectiveness: Simple distillation is particularly effective when the boiling point difference between the components is large. This allows for relatively easy separation of the components without the need for complex equipment or additional processing steps.
While molecular distillation, extractive distillation, and steam distillation are also distillation techniques, they are typically used for more specialized separation purposes and may involve additional steps or equipment beyond simple distillation.

B number of pumps and joining them in parallel.
C impeller diameter or speed.
D number of pumps and joining them in series,
ANS:D - all (a), (b) and (c).
The capacity of a centrifugal pump can be increased by:
- Increasing the impeller diameter or speed.
- Increasing the number of pumps and joining them in parallel.
Explanation:
-
Impeller Diameter or Speed:
- Increasing the diameter of the impeller or increasing the rotational speed of the pump will increase the kinetic energy imparted to the fluid. This leads to an increase in flow rate (capacity) through the pump.
-
Number of Pumps in Parallel:
- When multiple pumps are operated in parallel (side by side), the combined flow rate is the sum of the flow rates of each individual pump. This effectively increases the total capacity of the pumping system.
-
Number of Pumps in Series:
- When pumps are operated in series (one after another), the head generated by each pump adds up, but the flow rate remains the same as that of a single pump. Operating pumps in series is primarily used to increase the total head rather than the flow rate.
-
All (a), (b), and (c):
- While increasing impeller diameter or speed directly increases flow rate, and operating pumps in parallel also increases flow rate, operating pumps in series primarily increases head rather than flow rate. Therefore, option (c) is not entirely correct.
Conclusion:
The correct answer is (a) and (b):
- Increasing the impeller diameter or speed directly increases the pump's capacity.
- Increasing the number of pumps and joining them in parallel increases the total flow rate capacity of the pumping system.
