Flow rate,
Q = (P1 - P2) pi r^4/(8 n L)
105 x 10^-6 = [(101325 - P2) pi x 0.22^4 x 10^-12]/(8 x 10^-3 x 2.8)
Pressure, P2 = 3.19 x 10^8 Pa
Force, F = 3.19 x 10^8 x pi x (0.22 x 10^-2)^2
F = 4.86 x 10^3 N

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...
