$$ Sample Problem $8\mathrm{.}13$ The tanks, pump, and pipelines of Fig. $$8\mathrm{.}13$ have the characteristics noted. The suction line entrance from the pressure tank is flush, and the discharge into the open tank is submerged. If the pump $P$ puts $2\mathrm{.}0$ hp into the liquid, $($a$)$ determine the flow rate and $($b$)$ find the pressure in the pipe on the suction side of the pump.
