Question one

A valve is placed at the downstream end of a $2000$ m long pipeline. Water is initially flowing along a $300$ mm diameter and $10$ mm thick pipe at a velocity of $2\mathrm{.}0\frac{m}{s}$ and the valve is closed suddenly and completely. $E=2100{10}^8\frac{N}{m^2},K=2100{10}^6\frac{N}{m^2}$ and density, $=1000k\frac{g}{m^3}.$

a$.$ Considering that the pipe is rigid determine the magnitude of the surge generated. $(10$

b$.$ Considering that the pipe is elastic determine the magnitude of the surge generated. $(10$ marks$)$
