Chapter 14, Problem 37P

* A syringe is filled with water and fixed at the edge of a table at height h = 1.0 m above the floor (Figure P14.37). The diameter of the piston is $d_1=20.0\text{mm}$, the needle has length $L=50.00\text{ mm}$, and the inner diameter of the needle is $d_2=1.0\text{ mm}$. You press on the piston so that it moves at constant speed of $\text{10}\text{.00 mm/s}$. Determine (a) the distance D at which the water jet hits the floor and (b) the pressure difference between the ends of the needle Assume the viscosity of water is $\text{1}\text{.0 }\times {\text{ 10}}^{\text{-3}}{\text{ N• s/m}}^{\text{2}}$.
