Answer: 67.392s
Explanation: detailed calculation is shown below
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:
Yes the water will be safe at the point of cooling water discharge
Explanation:
Power losses in plant= 350- 350×0.35=227.5MW
Rate of heat rejection to stream= 0.75× 227.5= 170.625MW
Rate of heat rejection= rate of flow of water× c × ΔT
170625000= 150000000× 4.186 × (Final temperature- 20)
Final temperature= 20.3 ◦C
The final temperature of stream will be 20.3 ◦C. Thechange is very small so the minnows will be able to handle this temperature.

Answer:


Explanation:
The distance of the chain would be the product of the dislocation density and the volume of the metal.
Dislocation density = 
Volume of the metal = 



The chain would extend 
Dislocation density = 
Volume of the metal = 


The chain would extend
