A pump is used to pump water (=1000kg/m3,=0.001kg/m.s) from one large reservoir to another large reservoir that is at a higher elevation. The free surfaces of both reservoirs are exposed to atmospheric pressure as the figure below shows. The dimensions and minor loss coefficients are also provided below. The pump's performance is approximated by the expression " Havailable=H0aV2 ", where H0=40m of water column, .a=0.053m/(Lpm)2. Estimate the capacity delivered by the pump ( V in units of Lpm).(g=9.81m/s2) z2z1=6.7m(elevationdifference)D=3.0cm(pipediameter)KL,earanes=0.50(pipeentrunce)Kl,valve=2.0(valve1)Kl,valve=6.8(valve2)K,eltes=0.34(eachelbow-thereare3)KLexil=1.05(pipeexit)L=40m(totalpipelength)=0.0028cm(piperoughness)
