Chapter 6, Problem 12RQ

Which of the following statements about manifold gauge sets is not true?

  1. An adapter is required for using R-12 gauges on an R-134a system.

  • A manifold gauge set is used when discharging, charging, and evacuating and for diagnosing trouble in an A/C system.
  • The gauge manifold is designed to control refrigerant flow. When the manifold test set is connected into the system, pressure is registered on both gauges at all times.
  • R-134a service hoses have a black stripe along their length, the low-pressure hose is blue, and the high-pressure hose is red.
  • Blurred answer

    The six steps used to solve the Navier–Stokes and continuity equations for incompressible flow with constant fluid properties are listed below in random order. Identify the correct sequence of the steps according to their numbering to solve the equations. Write out and simplify the differential equations (continuity and the required components of Navier–Stokes) as much as possible. List all appropriate assumptions, approximations, simplifications, and boundary conditions. Solve (integrate) the differential equations. These lead to one or more constants of integration. Lay out the problem and the geometry. Identify all relevant dimensions and parameters. Verify the results by checking that the flow field meets all the specifications and boundary conditions. Apply boundary conditions to obtain values for the constants of integration.   Multiple Choice   3-5-2-1-6-4   5-2-3-1-4-6   1-3-2-4-5-6   4-2-1-3-6-5
    Consider liquid in a cylindrical tank. Both the tank and the liquid rotate as a rigid body as shown in the figure. The free surface of the liquid is exposed to room air. Surface tension effects are negligible. What are the velocity boundary conditions in terms of cylindrical coordinates (re, z) and velocity components (u, ug, U₂) at all surfaces, including the tank walls and the free surface? Determine velocity boundary conditions for the side wall. Free surface P = Patm Liquid R
    Consider the steady, two-dimensional, incompressible velocity field: V = (u, v) = (ax + b) i` + (−ay + c) j` where a, b, and c are constants. Identify the correct expression for the pressure as a function of x and y.
