The figure illustrates the flow of an ideal fluid through a pipe of circular cross section, with diameters of \( 1 \mathrm{~cm} \) and \( 2 \mathrm{~cm} \) and with different elevations. \( \mathrm{p}_{\mathrm{x}} \) is the pressure in the pipe, and \( v_{x} \) is the speed of the fluid at locations \( x=a, r, s, t \), or \( u \).
