Answer:
Power output,
Given:
Pressure of steam, P = 1400 kPa
Temperature of steam,
Diameter of pipe, d = 8 cm = 0.08 m
Mass flow rate,
Diameter of exhaust pipe,
Pressure at exhaust, P' = 50 kPa
temperature, T' =
Solution:
Now, calculation of the velocity of fluid at state 1 inlet:
Now, eqn for compressible fluid:
Now,
Now, the power output can be calculated from the energy balance eqn:
Answer:
The probable grain-coarsening mechanism is : Ideal grain growth mechanism
( -
= kt )
Explanation:
The plot attached below shows the time dependence of the growth of grain.
The probable grain-coarsening mechanism is : Ideal grain growth mechanism
the ideal growth follows this principle = = kt
d = final grain size
= initial grain size
k = constant ( temperature dependent )
t = 0
