Chapter 4, Problem 4.5.2P

The rate of flow in the pipe system in Figure is $\text{0}{\text{.05 m}}^{\text{3}}\text{/s}$. The pressure at point 1 is measured to be 260 kPa. All the pip are galvanized iron with roughness value of 0.15 mm. Determine the pressure at point 2. Take the loss coefficient for the sudden contraction as 0.05 and $\text{v = 1}{\text{.141 × 10}}^{\text{-6}}{\text{m}}^{\text{2}}\text{/s}$.
