John Satterly studied mathematics and physics at the University of London until 1901 and then was a research student at Cambridge University, from where he gained the PhD title in 1910; he was appointed in 1912 Lecturer in physics and promoted to associate professor in 1921 at the University of Toronto, Canada. From 1925, Satterly was a professor of physics at the University of Toronto, from where he retired in 1950. Satterly was a Fellow of the Royal Society of Canada and a Fellow of the Physical Society of London. His papers were published in the London Philosophical Magazine, in the Transactions of the Royal Society of Canada, and in the American Journal of Physics, among others.

Satterly had wide interests in science and engineering. In hydraulics, he contributed a number of papers to water jets. Using thin liquid jets under a range of angles from the horizontal, he and a collaborator derived experimentally that the jet had no perfect parabolic trajectory as was commonly assumed. In the 1937 paper it was found with model tests that the horizontal velocity component of such a liquid jet remained essentially constant from the point of issue to shortly upstream from the impact location. The jets investigated by Satterly were so small that effects of surface tension have certainly played an important role. After World War II, jets as typically used in hydraulic engineering were analyzed. The results answered the question why the US Navy had been so powerless in fighting against the fires following the Japanese air raid on Pearl Harbor in 1941, and added much to the use of trajectory spillways as an energy dissipator in hydraulic engineering.
