Given:

$D1=400mm\frac{O}{,}D2=200mm\frac{O}{?}$

$P1=150$kPa,$P2=90$kPa

Fluid passing the pipe $=$ water

$Q=0\mathrm{.}4m\frac{3}{s}$

a$.)$ Determine $F_H$ to hold the pipe elbow in equilibrium. $($and indicate its direction$)$

b$.)$ Determine $F_V$ to hold the pipe elbow in equilibrium. $($and indicate its direction$)$

c$.)$ Determine the new value of $F_V$ if you are to consider the weight of water in the control volume$)$ in the calculation.
