Water flows from a large tank through a large pipe that splits into two smaller pipes as shown in the figure below. The tip of the inclined pipe is at the same level as the bottom of the reservoir. If viscous effects are negligible, determine

$($a$)$ the flowrate from the tank,

$($b$)$ the pressure at point $(1).$

Assume $d_1=0\mathrm{.}08m,d_2=0\mathrm{.}05m,d_3=0\mathrm{.}03m,z=6m,$ and $h=4m.$

$($a$)Q=$

$\frac{m^3}{s}$

$($b$)p_1=$

kPa
