Answer:
drag coefficient for the parachute is Cd = 1.84177
Explanation:
given data
diameter = 8.0 m
average vertical speed = 3 m/s
total weight of load = 200 N
to find out
drag coefficient for the parachute
solution
we will apply here drag coefficient formula that is express as here Ā
drag coefficient Cd = [tex]\frac{2w}{\rho v^2A}[/tex] Ā Ā ......................1
here w is total load and A is area and v is speed
and here Ļ = 1.22 kg/cu
put here value we get Ā
Cd = [tex]\frac{2*4*200}{1.229*5^2*\pi * 3^2}[/tex] Ā
Cd = 1.84177
drag coefficient for the parachute is Cd = 1.84177
