Other factors that affect liquid flow rate include the liquid's viscosity and density, and the friction of the liquid in contact with the pipe. Direct measurements of liquid flows can be made with positive-displacement flowmeters. These units divide the liquid into specific increments and move it on.
And while the number of people dying while waiting for an organ transplant has decreased from 614 in 2011 to 469 in 2014, there have still been 195 individualsâ deaths this year after patients failed to find a donation in time.
However, since replacement organs are harvested from donor bodies, there is a continuous shortage of organs on offer, leading to long waiting periods for patients. In the United States alone, about 120,000 patients are on the waiting list. However, in 2012, there were only 14,013 organ donors and 28,052 subsequent transplant procedures. The World Health Organization (WHO) revealed that in 2010, a total of 106,879 organs were transplanted to patients globally â fulfilling only about 10% of the requirement.
