The value of Reynolds number R is 1.5. The coefficient of drag isa)8b)...
Explanation: When R<1.9, the value of coefficient of drag = 24/R
R=1.5, the coefficient of drag = 24/1.5 = 16.
R=1.5, the coefficient of drag = 24/1.5 = 16.

Explanation:
Reynolds Number:
- Reynolds number (R) is a dimensionless quantity used to predict the flow behavior of fluids.
- It is calculated using the formula: R = (ρ * v * L) / μ, where ρ is the density of the fluid, v is the velocity of the fluid, L is the characteristic length, and μ is the dynamic viscosity of the fluid.
Coefficient of Drag:
- The coefficient of drag is a dimensionless quantity that is used to quantify the drag force experienced by an object moving through a fluid.
- It is defined as the drag force acting on an object divided by the dynamic pressure of the fluid and the reference area of the object.
Calculation:
- Given R = 1.5
- For flow around a sphere, the drag coefficient (Cd) is given by Cd = 24 / R
- Substituting the value of R into the formula, Cd = 24 / 1.5 = 16
Therefore, the coefficient of drag for a Reynolds number of 1.5 is 16. This is the correct answer as per the given options.
