The Purdue Engineering Review PDF Download

Excerpt from The Purdue Engineering Review, 1914, Vol. 14 In Fig. 2, the curve a-a, co-ordinating external pres sures and lengths of the diaphragm, is determined experi mentally by varying the pressure surrounding the sealed diaphragm and noting the length. The curve b-b is also determined experimentally, and co-ordinates length of the diaphragm against internal pressure (gauge), and shows the internal-external pressure difference required to over come the elastic resistance of the walls of the diaphragm for various degrees of expansion. By adding the ordinates of these two curves we obtain the hyperbolic curve C-C, whose equation has the form X Y C. Solution of the curve locates the Y axis.
