Suppose that tank holds 1% liquid water by volume and 99% vapor water by volume at a temperature of 185oC. What is the quality?
1 answer:
Answer:
quantity = 0.645749
Explanation:
given data
holds liquid water = 1%
hold vapor water = 99%
temperature = 185°C
solution
we know that at temperature 185°C
Specific Volume of Saturated Liquid water (vf) = 0.0011343 m³/kg
and Specific Volume of Saturated Vapor (vg) = 0.17390 m³/kg
so quality will be
quality = ................1
put here value we get
quality =
quantity = 0.645749

Answer: The exit temperature of the gas in deg C is .
Explanation:
The given data is as follows.
= 1000 J/kg K, R = 500 J/kg K = 0.5 kJ/kg K (as 1 kJ = 1000 J)
= 100 kPa,
We know that for an ideal gas the mass flow rate will be calculated as follows.
or, m =
=
= 10 kg/s
Now, according to the steady flow energy equation:
= 5 K
= 5 K + 300 K
= 305 K
= (305 K - 273 K)
=
Therefore, we can conclude that the exit temperature of the gas in deg C is .
