specific speed [spə′sif·ik ′spēd]

(mechanical engineering)

A number,N_s, used to predict the performance of centrifugal and axial pumps or hydraulic turbines: for pumps,N_s=N√(Q)/H^3/4; for turbines,N_s=N√(P)/H^5/4, whereN_sis specific speed,Nis the rotational speed in revolutions per minute,Qis the rate of flow in gallons per minute,His head in feet, andPis shaft horsepower.
