Answer:
a) The slip coefficient is 0.9
b) Blade tip speed is 345.57 m/s
c) Stagnation temperature exiting the impellor is 416.84 k
d) Exit flow velocity is 84.88 m/s
e) Exit flow angle is 76.2°
f) Exit static temperature is 353.84 k
g) Impellor exit Mach number is 0.943
Explanation:
Flow at entry is axial α₁ = 0
Tagential velocity at entry 
= 0
Blade at exit is radial β₂ = 0
μ₂ = 
Answer:
power produced = 3098.52 kW
Explanation:
given data
insulated turbine = 100 bar
temperature = 400°C
pressure = 200 kPa
mass flow rate = 1.99 kg/s
solution
we use here steam table for At 100 bar and 400°C
h1 = 3096.5 KJ/Kg
and
at P2 = 200 Kpa
h2 = hf + 0.47 hg
h2 = 504.7 + 0.47 × 2201.6
h2 = 1539.452 KJ/Kg
so here
power produced is express as
power produced = m × (h1 - h2) .................1
power produced = 1.99 × ( 3096.5 - 1539.452 )
power produced = 3098.52 kW

Answer:
<h2> The overall reliability of the system is 88%</h2>
Explanation:
When solving for the reliability of a complex machine, that is a machine that has more than one component, the reliability of the machine is the products of all individual components.
Given the
reliabilities of 98%,
96%, and
94%
Converting to decimals we have
98/100= 0.98
96/100= 0.96
94/100= 0.94
The product of all reliability is
0.98* 0.96 0.94= 0.88
now converting back to percent we have
0.88*100= 88%
B) the plates are in constant motion and as a result the boundaries are where they interact
