Q2-An oil with a viscosity of u= 0.40 N s/m² and density p= 900 kg/m³ flows in a pipe of diameter d= 0.20m. (a) What pressure drop, pl-p2, is needed to produce a flowrate of Q=2.0×10-5 m/s if the pipe is horizontal with x1=0 and x2=10 m? (b) How steep a hill, 0 ,must the pipe be on if the oil is to flow through the pipe at the same rate as in part (a), but with pl=p2? (c) For the conditions of part (b), if p1=200 kPa, what is the pressure at section, x3=5 m, where x is measured along the pipe?

Question
Q2-An oil with a viscosity of u= 0.40 N-s/m² and density p= 900 kg/m³ flows in a pipe of diameter d=
0.20m .
(a) What pressure drop, p1-p2, is needed to produce a flowrate of Q=2.0×10-5 m²/s if the pipe is
horizontal with x1=0 and x2=10 m?
(b) How steep a hill, 0 ,must the pipe be on if the oil is to flow through the pipe at the same rate as in
part (a), but with pl=p2? (c) For the conditions of part (b), if p1=200 kPa, what is the pressure at
section, x3=5 m, where x is measured along the pipe?
