Appendix A

Given the following information

Distance between town main and sump tank $=150m$

Ball float valves pressure lost $=5m$

Residual pressure for tanks $($sump$,$ transfer and roof tank$)=2m$

Water meter head loss $=1m$

Pressure available from town main $=30m$

Pipe length:

Pipe $1-120m$

Pipe $2-140m$

Pipe $3-20m$

Pipe $4-25m$

Pipe $5-5m$

Use tabular method for pipe sizing for internal pipe $($i$.$e$.$ inside the toilet$)$ and use the

method outlined in section $4$ of the Piping system design for main pipe $($on schematic

diagram$).$

Determine:

$($i$)$ The size of sump and roof tank

$($ii$)$ The size of pipe $1$ to pipe $5$

$($iii$)$ The inlet pipe from town main

$($iv$)$ The pump head and flow requirement and its power rating

$($v$)$ The size and pressure requirement for pneumatic tanks $($Assume twin tanks$)$

$($vi$)$ Location of pressure reducing valve set

$($vii$)$ Revised the schematic diagram to reflect the above calculation resultsGiven the following information Distance between town main and sump tank $=150$m Ball float valves pressure lost $=5$m Residual pressure for tanks $($sump$,$ transfer and roof tank$)=2$m Water meter head loss $=1$m Pressure available from town main $=30$m Pipe length: Pipe $1-120$m Pipe $2-140$m Pipe $3-20$m Pipe $4-25$m Pipe $5-5$ m Use tabular method for pipe sizing for internal pipe $($i$.$e$.$ inside the toilet$)$ and use the method outlined in section $4$ of the Piping system design for main pipe $($on schematic diagram$).$ Determine: $($i$)$ The size of sump and roof tank $($ii$)$ The size of pipe $1$ to pipe $5($iii$)$ The inlet pipe from town main $($iv$)$ The pump head and flow requirement and its power rating $($v$)$ The size and pressure requirement for pneumatic tanks $($Assume twin tanks$)($vi$)$ Location of pressure reducing valve set $($vii$)$ Revised the schematic diagram to reflect the above calculation resultsFemale Toilet Male Toilet
