Answer:
B.197 gpm and 12.4 L/s
Explanation:
Given that
Load Q = 404.5 KW
Water inlet temperature= 6.1 °C
Water outlet temperature= 13.9°C
We know that specific heat for water
Now from energy balance
by putting the values
(1 Kg/s = 15.85 gal/min)
We can say that
We know that
12.38=1000 x volume flow rate
So
volume flow rate = 12.38 L/s
So the option B is correct.
Answer:
the critical flaw length is 10.06 mm
Explanation:
Given the data in the question;
plane strain fracture toughness = 92 Mpa√m
yield strength σ = 900 Mpa
design stress is one-half of the yield strength ( 900 Mpa / 2 ) 450 Mpa
Y = 1.15
we know that;
Critical crack length = 1/π(
/ Yσ )²
we substitute
= 1/π( 92 Mpa√m / (1.15 × 450 Mpa )²
= 1/π( 92 Mpa√m / (517.5 Mpa )²
= 1/π( 0.177777 )²
= 1/π( 0.03160466 )
= 0.01006 m = 10.06 mm
Therefore, the critical flaw length is 10.06 mm
{ = ( 10.06 mm ) > 3 mm
The critical flow is subject to detection
