Answer:
0.2108
Explanation:
WA = 0.245 x 0.045 = 0.011025 m2. Then, LER = 0.011025/0.0523 = 0.2108.
Answer:
speed of air is 200 m/s
Explanation:
given data
length dl = 10 m
diameter dp = 2 m
maximum allowable speed Vp = 10 m/s
scale = 1/20th
to find out
speed of air in the tunnel to achieve dynamic similarity
solution
we know in dynamic similarity ratio of force at corresponding point in model are equal and different dimensionless no is use for dynamic similarity
so
Rem = Rep
Re is modal law
so
and
VpDp = VmDm
so
so
10 ×
Vm = 200 m/s
so speed of air is 200 m/s
Answer: sustainable design engineering
Explanation:
Based on the scenario, the type of engineering that identifies Greg's role in Ethiopia is referred to as sustainable design engineering.
Sustainable engineering is referred to as the process of designing systems or operating them in such a way that the resources and energy are utilized sustainably and conserving them so that the natural environment will not be compromised and such resources will be available for the future generations.
