Ultrasonography of the Biliary Tract,the square of the circumferential rotor speed. By contrast, positive displacement pumps (e.g. piston pumps) essentially deliver the same volume Vstroke at each stroke independently of flow velocity or rotor speed n. The flow rate then becomes Q = nxV.; the pressure rise results solely from the imposed back pressure.
