A piston pushes 20 ∘C water through a horizontal tube of 0.23 −cm radius and 2.7 m length. One end of the tube is open and at atmospheric pressure. Determine the force needed to push the piston so that the flow rate is 105 cm3/s . The viscosity of water at this temperature is 1.0 ×10−3 N⋅s/m2. Express your answer with the appropriate units. Repeat the problem using SAE 10 oil instead of water. The viscosity of oil is 0.20...
