Answer:
Explanation:
Hello,
In this case, for the inlet stream, from the steam table, the specific enthalpy and entropy are:
Next, for the liquid-vapor mixture at the outlet stream we need to compute its quality by taking into account that since the turbine is adiabatic, the entropy remains the same:
Thus, the liquid and liquid-vapor entropies are included to compute the quality:
Next, we compute the outlet enthalpy by considering the liquid and liquid-vapor enthalpies:
Then, by using the first law of thermodynamics, the maximum specific work is computed via:
Best regards.
Answer:
(a) 0.1509 mm
(b) 0.00525 mm
Explanation:
Stress, 
is given by
where F is force and A is area and area is given by 
hence
where d is the diameter. Substituting 9970 N for F and 10mm=0.01 m for d hence
From the attached stress-strain diagram, the stress of 127 Mpa corresponds to strain of 0.0015 and since strain is given by
where
is the strain, 
is elongation and l is original length and making elongation the subject
and substituting strain with 0.0015 and length l with 100.6 mm then
(b)
Lateral strain is given by
and substituting 
for 
where v is poisson ratio then
and making 
the subject then
and substituting 0.35 for v, 0.0015 for strain and 10 mm for d
and the negative sign indicates decrease in diameter
Answer:
What you should do changes based on the hazards you're exposed to.
You should be aware of any hazards that are present.
Safety devices can help decrease force taken during a crash they also keep u in place and protected overall
