CH ENGR 101A Quiz: 2017 Homework 5
Document Summary
Water flow through the pipe contraction as shown in the figure below. for the given 0. 2-m difference in the manometer level, determine the flowrate as a function of the diameter of the small pipe, d. A pitot-static tube is used to measure the velocity of helium in a pipe. The temperature and pressure are 40 f and 25 psia. A water manometer connected to the pitot-static tube indicates a reading of 2. 3 in. Water is siphoned from a large tank and discharges into the atmosphere through a 2-in. -diameter tube. Atmospheric pressure is 14. 7 psia, and the water vapor pressure is 0. 26 psia. Problem 4 (a) show that for poiseuille flow in a tube of radius r the magnitude of the wall shearing stress, rz , can be obtained from the relationship ( for a newtonian fluid viscosity . rz wall.
