$3.$ The horizontal tee connection shown in FIGURE Q$3$ is used for distribution of water $(=998k\frac{g}{m^3})$ in a coastal village. It has an internal diameter of $1$ m $.$ The water flow is steady and frictionless.

a$.$ Ultrasonic flowmeters with a capability to measure in a range of $4\mathrm{.}1\frac{m^3}{s}$ to $10\mathrm{.}9\frac{m^3}{s}$ will be installed at Sections $(1).(2)$ and $(3)$ to assure constant water flow rates. Assess the suitability of the flowmeters.

b$.$ Determine the differential pressure between Section $(2)$ and Section $(3).$

c$.$ The force resulted by the flowing water may cause the tee to shake. Elaborate the steps required to sufficiently hold the tee in place.

d$.$ A few years later, due to global warming, part of the village is flooded causing the pipe system to be submerged. The anchors in part $($c$)$ probably cannot sustain the resulting force. Create an action plan in order to keep the piping system operating safely.
