Question $1$

Water at $20$oC flows through a tube with a diameter of $0\mathrm{.}6$ cm and $30$ m long at a flow rate of $0\mathrm{.}34$ liters$/$min$.$ If the pipe discharges to the atmosphere, determine the supply pressure if the tube is inclined $10$o above the horizontal in the flow direction.

$$ Water properties: r $=998$ kg$/$m$3,$ g $=9\mathrm{.}81$ m$/$s$2,$ kinematic viscosity $($n$)=1\mathrm{.}005$ x $10-6$ m$2/$s
