Situation $9-$ In a laboratory constant head permeability test, a cylindrical Situation $11-$ fire pump delivers water through $180$ m of $150$ mm main to a hydrant which is connected to a $63\mathrm{.}5$ mm hose $76$ m long ending in a $25$ mm nozzle. The nozzle is $1\mathrm{.}50$ m above the hydrant and $4\mathrm{.}60$ m above the pump.
