DetailsNow knowing pc we can calculate the radial expansions and the stresses if desired For instance the produces a negative volume change It can be shown that for isotropic materials the bulk 10 What pressure is needed to expand a balloon initially 3 in diameter and with a wall thickness of 01 to a diameter of 30 The balloon is
DetailsPipe Pressure Drop Calculations When fluid flows through a pipe there will be a pressure drop that occurs as a result of resistance to flow There may also be a pressure gainloss due a change in elevation between the start and end of the pipe
DetailsSurge pressures or pressure surges occur in a pipe transporting fluid as a result of a change in the flow velocity e g if a valve is closed or opened too rapidly If a valve is closed rapidly the energy of the fluid moving forward in the pipe leads to a sudden rise in pressure due to compression upstream of the valve Negative pressure will develop immediately downstream of the valve as
