A cold storage plant is a facility used to store perishable food items like fruits, vegetables, meat, fish, and dairy products at low temperatures.
The main components shown in the layout are:
1. Compressor: Compresses the refrigerant to high pressure.
2. Condenser: Removes heat from the refrigerant and converts it to liquid.
3. Receiver: Stores liquid refrigerant.
4. Expansion valve: Reduces the refrigerant pressure before entering the evaporator.
5. Evaporator: Absorbs heat from the cold storage room, keeping it cool.
6. Cold storage chamber: The insulated space where goods are stored.
7. Fans: Circulate cold air evenly inside the storage room.
A labelled diagram should show all these components connected in the correct sequence.
For the curve \( \sqrt{x} + \sqrt{y} = 1 \), find the value of \( \frac{dy}{dx} \) at the point \( \left(\frac{1}{9}, \frac{1}{9}\right) \).
