221. Velocity profiles are measured at the upstream end (surface 1) and at the downstream end (surface 2) of a rectangular control volume, as shown in Fig. P2.21. If the flow is incompress- ible, two dimensional, and steady, what is the drag coefficient for the airfoil? The vertical di- mension H is 0.025c. The pressure is poo (a constant) over the entire surface of the control volume. (This is an extension of Problem 2.9.) 3)-r u=U, H 0.02501 Figure P2.21
Velocity profiles are measured at the upstream end and at the downstream of a 2D channel as shown in the Figure. The horizontal lines indicate the upper and lower walls. The velocity profile at the inlet is U=Uo while at the outlet the velocity has the distribution shown in the figure (2 linear regions near the two walls and a region where the velocity is constant in the center). =U. The pressure at the inlet is P.-P+pU? If the flow...
A wing is mounted in the center of a wind tunnel's rectangular test section of height H and span b. Velocity profiles are measured upstream and downstream of the test section. The wing is generating a wake of extent H/4, with a minimum velocity Viv/2 measured in the centerline. The velocity in the wake linearly increases to VoUTEXT and then remains uniform up to the test section walls. a) Calculate the ratio between VoUTEXT and VIN considering the flow to...
summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...

Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...
