Answer:
a)initial quality of water 0.724.
b)mass of water =2.45 kg
c)T=70°F
Explanation:
h=732.5 Btu/lbm
h=763.33 KJ/kg (1 Btu=1.05 kj)
T=70°F⇒T=21.1°C
(a)From steam table
Properties of saturated steam at 21.1°C
To find dryness fraction
x=0.27
So initial quality of water 0.724.
(b)
where v is specific volume
From steam table at 21.1°C
V=
0.002458=
So mass of water =2.45 kg
(c)
Actually water will take latent heat ,it means that heating of will take place at constant temperature and constant pressure.So we can say that final temperature of water will remain same (T=70°F).

Answer:
The speed of the aircraft is
Explanation:
Assumptions.
1. flow of air is steady & incompressible.
2. Frictional effects are neglected.
From the Bernoulli's equation
The velocity of the jet is given by
Here
Thus velocity
Therefore the speed of the aircraft is
