Water will be pumped from a reservoir free surface of which isat an elevation of “z1†to reservoir the free water surface ofwhich is at “z2â€. Both of the reservoirs’ free surfaces atatmospheric pressures.Design a piping system that transmits waterfrom the lower reservoir to the upper reservoir at a volumetricflow rate of Q (m3 /h).
Q = 200 (m3/h) Za = 10(m) Zb= 60 (m) Zc = 75 (m) L1=200 (m)L2=125 (m) \"Pipe material is \"Commercial Stainless Steel\" \"
1) Consider necesssary fittings( valves, elbows….)
2) Given data and cost elements, determine the optimum pipediameter of the system . In order to do this:
3) Write the energy equation between z1 and z2 by taking themajor losses associated with the pipe, minor losses associated withthe fittings, sudden contraction, and expansion regions inside thesystem and the pump total head rise â€hp†into account .
4) The average velocity of the water inside your piping systemshould be between 0.1 and 5 m/s. 5) Calculate the head rise “hpâ€that must be provided by the pump.
6) Choose a pump that provides a head rise of â€hp†(that youcalculated) near its most efficient working flow rate at your givenflowrate Q from the local manufacturer’s catalogues.
7) Find the cost of the pipe per one meter (TL/m) and unitelectricity price ( TL/kWh). Neglect cost of the pump or pumps.
8) Calculate the cost of the system for one year: Obtain thegraph which shows the variation of the capital cost, the energycost and the total cost in function of the pipe diameter forworking of the pump at a rate of 24 hours/day for one year.
9) If head loss from reservoir to pump inlet is 0.8 m, whereshould the pump inlet be placed to avoid cavitation for water at15°C, pv= 1.71 kPa absolute?.
10)Check the absolute pressure at point C.
11) Draw a schematic representation of the system.
12) Give necessary technical drawings of the pipe and giveschematic representations of the chosen minor loss elements.
13) Give the performance characteristics chart of the chosenpump and the technical drawing of it.
