"A method of determining the response of fluids under high pressure to quick-release into the atmosphere is presented in this report. The analytical efforts have been formulated into two parts, a closed-form solution and a numerical analysis. By assuming constant viscosity of the fluid a closed-form solution was obtained. The assumption of constant viscosity was found to be acceptable for the test fluids up to an initial pressure of approximately 10,000 psi. A numerical analysis became necessary for initial pressures over 10,000 psi, where the variable viscosity of the fluid had to be considered. The experimental work was conducted by observing the flow of a fluid from a pressurized reservoir through a circular tube to the atmosphere. The primary experimental variables were: (1) length of the circular tube, (2) type of fluid used, and (3) initial reservoir pressure. The pressure decay was measured by the use of strain gages in the reservoir and recorded on an oscilloscope screen"--Abstract, Page ii.
