Example $3$

A $300$ mm diameter pipe carries water under a head of $20$ meters with a velocity of $3\mathrm{.}5\frac{m}{s}.$ If the axis of the pipe turns through $45,$ find the magnitude and direction of the resultant force at the bend.

$\frac{p}{g}=20m$

$p=20g=2010009\mathrm{.}81\frac{N}{m^2}=196200\frac{N}{m^2}$
