Questions:

1.Field  notes  and  traverse  drawing  may  be  an  outdated  form  of  keeping  and  presenting information  on  the  position  of  features  on  a  site.  Modern  electronic  equipment  and computer  based  processing  will  inevitably  supersede  the  traditional  technique,  but  any technique does require the understanding of position and relative association which is the basis  of  the  modern  alternatives.  In  completing  the  following  task,  you  gain  some knowledge of the concepts of the traverse and gain experience of using CAD software ina different way.

The following field notes(3sheets)  ofan investigation survey for a  proposed  servicestation sitehave been compiledbya surveyor.

Using CAD software, producea drawingofthetraverseshowing all theinformationonthesite.

2.Some  of  the  Remote  Access  Laboratory  equipment  in  the  Hydraulics  Lab  at  USQ  were designed  and  built  in-house.  An  experiment  to demonstrate  and  measure  the  force  resulting from  a  jet  of  water  impacting  surfaces is  depicted  in  the  schematic  of Figure .  Use  this schematic in conjunction with the following operating requirements,

•240VACsupplies  a  PC  for  the  Human-Machine-Interface  (HMI), a  thermostat-switched 240VACcooling fan,

a 240VACPLC-controlled pump,

a 240VACto 24VDCsupply and

a 240VACto 12VDCsupply

24VDCsupplies the PLC, Load CellTransmittersand Ball Valve V-1

12VDCsupplies ancillary lighting and PLC E/stop

The experiment is commencedby  starting Centrifugal Pump E1 while Electronically Actuated Ball Valve V-1 is closed. Water Pressure Switch S-1 is used to check thatE-2is producing pressure.Together withFloat Switch S-5, this confirms that E-2 can be safely operated

.•The Flat Impact Test or the Cup Impact Test are selected by operating either Angle Seat Valves, V-2 or V-3using a signal from the HMI.

•ButterflyValve V-4 is openedand the output from Load Cell S-4 is monitored until a steady load is measured.A desired anticipated flow rate is set as an input to V-1, sent from the HMI (e.g. 30% of full deflection).

•Once steady conditions are measured at S-4, V-4 is closed until an additional prescribed mass of water accumulates in the Mass Measurement Tank. At this point, V-4 is opened and the length of time that it took to accumulate the mass is recorded by the PLC.This allowsa  precise  calculation  of  the  mass  flow  rateof  the  jet  of  waterimpacting  the surface

•While the Mass Measurement Tank is filling with the set and measured flow, Load Cell S-2 or S-3 measures the force applied to the surface the jet of water impacts. This data is recorded for subsequent analysis.

•Additional  data  is  collected  for  various  setting  of  V-1.  Once  the  desired  data  is collected,V-1 is closed and E-2 is stopped.

•The remote HMI Control uses one PLC using fourinputs to produce the data used to calculatethe experiment’s results.

•For safety purposes an emergency stop pushbutton isolates ACpower via a safety relay (except control power to the PLC) when pressed.
