This is as if the fluid has no viscosity, so the force you have to apply over the distance is only due to the kinetic energy required to expell the fluid. To accommodate a first fixing member, an appropriate first bore is inserted into the elongate tubes proximal end. It is possible to reach the inner surface of the first fixing member with the lubricant. For this case, I will consider $h_f =0$ (ideal case), $$\dfrac{P_1}{pg} = \dfrac{P_2}{pg} + \dfrac{1}{2}\dfrac{V_2^2}{g}$$, $$(P_1-P_2) = \delta P = \dfrac{1}{2}pV_2^2$$.
