Problem 19P

A 90° elbow in a horizontal pipe is used to direct water flow upward at a rate of 30 kg/s. The diameter of the entire elbow is 10 cm. The elbow discharges water into the atmosphere, and thus the pressure at the exit is the local atmospheric pressure. The elevation difference between the centers of the exit and the inlet of the elbow is 40 cm. The weight of the elbow and the water in it is considered to be negligible. Determine (a) the gage pressure at the center of the inlet of the elbow and (b) the anchoring force needed to hold the elbow in place. Take the momentum-flux correction factor to be 1.03 at both the inlet and the outlet.

Bio Notes 8/29 CHAPTER 3-WATER • a solution is a liquid that is a completely homogenous mixture of substances • a solvent is the dissolving agent of solution • the solute is the substance that is dissolved • An aqueous solution is one in which water is the solvent • Water is a versatile solvent due to its polarity • When an ionic compound is dissolved in water, each ion is surrounded by a sphere of water cells (hydration shell) • Hydrophillic- can interact w water • Hydrophobic- does not interact w water (oil) • Molecular mass- all the mass in a molecule • Molarity (M)- number of moles of solute per liter of solution • 6.02x10^23 daltons=1 g • An acid is any substance that increases the H+ concentration of a solution • A base
