Answer:
the quality of the refrigerant exiting the expansion valve is 0.2337 = 23.37 %
Explanation:
given data
pressure p1 = 1.4 MPa = 14 bar
temperature t1 = 32°C
exit pressure = 0.08 MPa = 0.8 bar
to find out
the quality of the refrigerant exiting the expansion valve
solution
we know here refrigerant undergoes at throtting process so
h1 = h2
so by table A 14 at p1 = 14 bar
t1 ≤ Tsat
so we use equation here that is
h1 = hf(t1) = 332.17 kJ/kg
this value we get from table A13
so as h1 = h2
h1 = h(f2) + x(2) * h(fg2)
so
exit quality = 
exit quality = 
so exit quality = 0.2337 = 23.37 %
the quality of the refrigerant exiting the expansion valve is 0.2337 = 23.37 %

Chlorophyll is responsible for the green color of plants.Photosynthetic organisms capture energy from the sun and matter from the air to ... oxygen produced during photosynthesis makes leaf bits float like bubbles in water. ... their ability to carry out photosynthesis, the biochemical process of capturing ... this air is forced out and replaced with solution, causing the leaves to sink.
Answer:
The sentence excerpted from the e-mail uses passive voice.
Given the purpose of your message, this voice is appropriate.
Explanation:
Because the objective is to remedy the situation a passive voice is great because it emphasizes the action and the object instead of the subject.
We want to emphasize the document and the incorrect information, not our colleague.
Answer:
The angular velocity is 7.56 rad/s
the maximum water height is 2 ft
Explanation:
The z-position as a function of r is equal to
(eq. 1)
where
h0 = initial height = 1 ft
w = angular velocity
R = radius of the cylinder = 1.5 ft
zs(r) = 0 when the free surface is lowest at the centre
Replacing and clearing w
if you consider the equation 1 for the free surface at the edge is equal to
