This is why cord blood can be used for transplantation as an alternative to bone marrow. Cord blood is being used increasingly on an experimental basis as a source of stem cells, as an alternative to bone marrow. Most cord blood transplants have been performed in patients with blood and immune system diseases.
(= (S + (p. . Solute potential is at a maximum at zero (distilled water), whereas pressure potential can be negative (vacuum), zero (one atmosphere), or positive (greater than zero). So distilled water at normal atmospheric pressure has a water potential of zero ((= 0).
So whatâs the difference? Looking at the fundamental vacuum relationship Q=SP, we have. Gas Load = Pumping Speed x Pressure, or Mass Flow = Volume Flow x Pressure. Volume Flow. Volume flow is most commonly used to describe and quantify pumping speeds. Most commercial sales literature for pumps will provide a pumping speed vs. pressure curve. The figure shows some examples.
