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

Explanation:
Answer:
50%
Explanation:
<u>Given information</u>
Cooling load=50 kW
COP=2
Consumption=50 kW
<u>Calculations</u>
Revised input is given by cooling load/COP=50/2=25 kW
Efficiency= Work output/ Revised input=25/50=0.5
Efficiency=0.5*100=50%
Answer:
Option D
Explanation:
As we know
Gravitational Constant (G)
Mass of Earth (M)
Weight of satellite (m) Kg
Radius of Earth (R) =
Distance of satellite from Earth =
Substituting the given values, we get
Km
or 635 m
The correct answer is option D
