An oil with a viscosity of u = 0.40 N-s/m? and a density of p = 900 kg/m flows in a pipe of diameter D = 0.020 m. (a) What pressure drop, P.- PL is needed to produce a flowrate of Q = 2.0 x 10 m'/s if the pipe is horizontal with a length of 10 m? Express your answer in kPa. (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 P. = PL?
