Answer:
The density of Saturn is 686.81 kg/m³.
Explanation:
Mass of Saturn,
Volume of Saturn,
Density of Saturn is given by its mass divided by its volume i.e.
So, the density of Saturn is 686.81 kg/m³.
The density of water is 1000 kg/m³. It is clear that the density of Saturn is less than water.
Answer:
The the quality of the refrigerant at the exit of the expansion valve is 0.179.
Explanation:
Given that,
Initial pressure = 10 bar
Temperature = 22°C
Final pressure = 2.0 bar
We using the value of h
The refrigerant during expansion undergoes a throttling process
Therefore,
We need to calculate the quality of the refrigerant at the exit of the expansion valve
At 2.0 bar,
The property of ammonia
Using formula
Put the value into the formula
Hence, The the quality of the refrigerant at the exit of the expansion valve is 0.179.
