Oil is pumped over a distance of 1.5km through a 75mm diameter tube at a rate of Q=25000kg/h. SG=0.9 and kinematic viscosity v=0.00033 m2/s The Dynamic viscosity is 1. =waterSGv=0.297Ns/m2 2. =waterSG/v=0.297Ns/m2 3. =waterSGv=0.297Nsm2 4. =water/SGv=0.297Ns/m2 The Reynolds number is 1. Re=4Q/(Dv)=396.8 2. Re=4Q/D=396.8 3. Re=Q/(Dv/4)=396.8 4. Re=Q/(D2U)=396.8 1 and 3 2 and 3 2 and 4 1 and 2 Hagen-Poiseuille's equation is 1. p=D3128DLQ=4424663N/m2 2. p=D4128DLQ=4424663N/m2 3. p=D432DLQ=4424663N/m2 4. p=D4128DLQ=4424663Pam 2 4 1 and 4 2 and 3 the head lost is 1. hl=p=501.16m 2. hl=D4128DLQ=501.16m 3. hl=D4128DLQ=501.16Pa 4. hl=D3128DLQ=501.16m
