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.
Together we can save more people. We manage the NHS Organ Donor Register and National Transplant Register, which lets us fairly match donors to people who are waiting for a transplant. Thanks to our amazing donors, we were able to facilitate more transplants in 2016/17 than ever before. This is fantastic, but there is still lots to do. There are currently around 6,500 people on the UK transplant waiting list. Last year, nearly 500 people died while waiting for a transplant.
