The air inside a space capsule is maintained at the required condition by passing it through a set of heat exchanger. The heat exchangers are designed such that the humid air passing through them is cooled and partial condensation of the water vapour occurs. On a psychrometric chart, this process appears as a line which is?

Horizontal to the left
Vertical downwards
Diagonal downwards to the left
Diagonal upwards to the right

Option 3 : Diagonal downwards to the left

Concept:

[ alt="Capture2012" src="//storage.googleapis.com/tb-img/production/17/05/Capture2012.PNG" style="height:148px; width:171px">

In the figure, it shows that,

OA → Sensible heating

OB → Sensible cooling

OC → Humidification

OD → Dehumidification

OE → Heating + humidification

OF → Cooling + dehumidification

OG → Cooling + humidification

OH → Heating + dehumidification

In heat exchangers, the humid air is cooled, and (partial condensation) dehumidification is taking place. So the OF will be the process which is diagonal to the left side in a downward direction.

Given below are two quantities named A and B. Based on the given information, you have to determine the relation between the two quantities. You should use the given data and knowledge of Mathematics to choose between the possible answers. There are two jars which contain different liquids in different quantities Quantity I∶ Quantity of water in Jar 1, if Jar 1 contains mixture of 230 litres which contain juice, water, coke and pepsi. Ratio of quantity of water to juice is 2 : 1 and juice to coke is also 2 ∶ 1 while the ratio of quantity of coke to pepsi is 3 ∶ 2 Quantity II∶ Quantity of water in Jar 2, if Jar 2 contains 10 litres of mixture more than jar 1 and contains juice, coke and water. Water, juice and coke is poured into the jar 8 times in the ratio 3 ∶ 2 ∶ 1. Every time the quantity of a liquid is same.?

In the following question the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/passage and find out which of the four combinations is correct.. 1. Industrially raised chicken can be abnormally forceful, and are regularly kept in obscured sheds to avoid them pecking at each other. P. The feathered creatures invested much a greater amount of their energy—up to a third—pecking at the lifeless things in the pens, as opposed to fowls in different pens which invested a considerable measure of time assaulting others. Q. In low light conditions, they carry on less pugnaciously, yet are more inclined to ophthalmic scatters and respiratory issues. R. In an examination, forceful head-pecking was everything except killed among fowls in the improved condition. S. Modifying the birds’ condition, by adding parcels of wood-shavings to their pens, can work wonders. 6. Bundles could lessen forcefulness and decrease wounds; they may even enhance efficiency, since a glad chicken is a profitable chicken.?
