A viscous fluid flows in two different pipes. Pipe 1 has a radius r1, and Pipe 2 has a radius r2. If both pipes have the same length and r1 > r2, choose the correct statement about the pressure difference of the fluid in Pipe 1 and Pipe 2 The pressure difference of the fluid is the same in Pipe 1 and Pipe 2. The fluid in Pipe 1 has larger pressure difference. It cannot be determined in which pipe the fluid has larger pressure difference. The fluid in Pipe 2 has larger pressure difference.
1. A capillary tube of inside diameter d=6mm connects tank A and open container B as shown in Fig.2. The liquid in A,B and capillary CD is water having a specific weight y=9780 N/m³ and a viscosity of μ=0.0008N s/m². The pressure PA-34.5 kPa gage. Neglecting the minor losses at C and D, determine the flow rate Q through the capillary tube. Assume laminar flow from A to B and use h=32μLV/yd² for the friction loss, where V is the water velocity through the capillary tube.

1. Suppose a person is 182 cm tall. A typical blood pressure is often given as 110/70 mm Hg, with a mean pressure of 80 mm Hg. A. Do you think this is the gauge pressure or absolute pressure? Why? If the pressure at the top of the head is about 39 mm Hg, how far away is this person's head from the heart? Assume the density of blood is about 6% higher than that of water. t, What then would be the blood pressure.of this 6, person at their feet? b. Suppose this person suffers a puncture wound around the same height as the heart where the opening is about 3 mm in diameter. How far could blood shoot from their body assuming it comes out horizontally with 0 m/s initial horizontal velocity? %3D = 0.754 Since horizontal velocity is zero it will not go eny for than body Please explain the variábles used in the equation to solve for F= P.A in partad of this question.
