Using your answer for Q , show that x ¨ 2 ± ± 4 P P = 8 Q a dx 1 2 S x 1 where P and P are the pressures at x and x . 1 2 1 2 4. Assume the tube radius is given by a x 1 ( ) = + D x , where is a constant. Obtain an equation for the pressure gradient ± G x ( ) assuming the pressures P and P are known at 1 2 points x and x . Express your answer in terms of x 1 , x 2 , P , P 2 , and x . 1 2 1 5. If = 0 , what is the pressure gradient? 1...
