Which parameter change most reliably laminarizes a pump's turbulent flow?

A)Increase fluid dynamic viscosity✓

B)Reduce the impeller turbulence cascade

C)Increase volume flow magnitude vastly

D)Decrease pipe surface roughness marginally

💡 Explanation

Laminarizing turbulent flow typically requires reducing the Reynolds number; *increasing viscosity* does this directly, because it damps eddy formation. Therefore increasing viscosity is ideal rather than increasing flow which enhances turbulence; surface roughness has little effect.
