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:
The note in this question is not an instrument that is negotiable under Article 3 of the U.C.C. Furthermore, it is not payable at any given time on demand due to the fact that principal repayment is not covered at a specified period of time. It shows that the acceleration clause is viable for the payment of the amount upon the default of the maker. This is also for an indefinite period of time.

Answer:
Explanation:
Given
From Clausius inequality
=Reversible cycle
=Irreversible cycle
=Impossible
(a)For
Rejected heat
thus it is Impossible cycle
(b)
Possible
(c)Carnot cycle
and maximum Work is obtained for reversible cycle when operate between same temperature limits
Thus it is possible
Mechanical and electrical
Answer:
