Answer:
The drag force is
Explanation:
Given that,
Diameter = 60 cm
Length = 1 m
Air speed = 4.5 m/s
Temperature = 50°C
We need to calculate the Reynolds number
Using formula of Reynolds number
Put the value into the formula
We need to calculate the drag coefficient
Using formula of drag coefficient
Put the value into the formula
We need to calculate the drag force
Using formula of drag force
Put the value into the formula
Hence, The drag force is
