# Calculate the drag force

A sphere, 14.7 mm in diameter, drops at a rate of 0.08 m/s in oil
µ = 0.1 Ns/m^2 , σ = 0.85 ). Calculate the drag force acting on the sphere.

F_d=0.5*rho*C_d*A*u^2, Re=u*p*L/μ

I attempted to find the Re, but am struggling on finding the coefficient of drag now. Once I crack this I will be able to progress please help!
