Answer:
The text file attached has the detailed solution of all the parts individually.
the answer is (c)
After the vehicle is involved in a car accident or fire
Answer:
True
Explanation:
Wastewater should never be discharged into storm sewers. Storm sewers are constructed to store rainwater.
Rainwater passes through storm sewers to the nearest underground water resource if the wastewater discharge into storm sewers, then they will also pollute the ground water, so usually the dirty water is not put in the storm sewers.
Answer:
surface temp of fuel rod = 678.85 K
Explanation:
Given data :
D1 = 25 mm
D2 = 50 mm
T2 = 335 k
T∞ = 300 k
hconv = 0.15 w/m^2.k
ε2 = 0.05
ε1 = 1
Determine energy at Q23
Q23 = Qconv + Qrad
attached below is the detailed solution
Insert given values into equation 1 attached below to obtain the surface temperature of the fuel rod ( T1 )
Answer:
W = 11,416.6879 N
L ≈ 64.417 cm
Explanation:
The maximum shear stress, 
, is given by the following formula;
= 1 cm = 0.01
h = 29 cm = 0.29 m
= 25 cm = 0.25 m
b = 15 cm = 0.15 m
= The centroidal moment of inertia
= 1/12*(0.15*0.29^3 - 0.15*0.25^3 + 0.01*0.25^3) = 1.2257083 × 10⁻⁴ m⁴
Substituting the known values gives;
= 1.2257083
× 10⁻⁴ m⁴
From which we have;
Which gives;
W = 11,416.6879 N
= 1500 N/cm² = 15,000,000 N/m²
= 15,000,000 × 1.2257083 × 10⁻⁴ ≈ 1838.56245 N·m²
From Which we have;
L ≈ 0.64417 m ≈ 64.417 cm.
