Solve 2nd question

A fluid is pumped through a curved pipe. At the lower part, the fluid flows with a speed v; = 1.21 m/s through the center of a section of the pipe with radius r; = 0.07 m. At the upper part, the fluid flows with a speed v2 through the center of a section of the pipe with radius r2= 0.19 m. The center of the upper part of the pipe is higher than the center of the lower part of the pipe by a height H = 1.43 m. The density of the fluid is 989 kg/m?. 1) What is v2, the speed of the fluid flow in the center of the upper part of the pipe? m/s i 2) If the pressure at the center of the lower part of the pipe is P; and the pressure at the center of the upper part of the pipe is P2, what is P; - P2? wy
