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.
Thousands of lives depend on receiving organs and tissues for transplant, but there is a severe and chronic shortage of donor organs. Every year, more than 1,500 people die waiting for a donated liver to become available. Currently, about 17,000 adults and children have been medically approved for liver transplants and are waiting for donated livers to become available. The waiting list grows every year. Only once an individual is declared âbrain deadâ can organs be retrieved to save the lives of others.
