An ideal gas is to flow isentropically from a large tank where the air is maintained at a temperature and pressure of 59 °F and 114 psia to standard atmospheric discharge conditions in a way to achieve a maximal velocity. Describe in general terms the kind of duct involved and determine the duct exit Mach number and velocity in ft/s if the gas is air. The problem can be solved either using the isentropic relations or this figure. The isentropic relations are more accurate, but difficult to use unless you code them into a computer program. (a) What is the pressure ratio for the flow? (b) Is the exit flow subsonic, sonic, or supersonic? (c) What is the exit Mach number? (a) Pexit/PO 0.1289 (b) supersonic (c) Mexit 1.99 eTextbook and Media Hint Part 2 x Incorrect. The temperature needs to be in degrees absolute. (a) What is the exit temperature?

Select the correct statements regarding the addition of moments. (Select 3) Moments have directions, so a negative value implies it is along the opposite direction from the reference direction. All the moments need to have the same reference point/pivot in order to add together. Calculate each moment by multiplying each force with its distance to the reference point, and add all values together, regardless of their direction. You have to define the reference direction first, either clockwise or counter-clockwise.

Required information Sally is making a sine bar, which is used to machine angles on parts (see the given figure). She has a 1.250-inch-thick bar that needs 90° grooves machined into it for precision ground 1.0000-inch diameter cylinders. A sine bar is used by placing different thicknesses under one of the cylinders so that the proper angle is attained. Sally wants the distance between the centers of the cylinders to be D= 5.9 inches. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. 7 -1.00000 * How deep should she mill the 90° grooves so that the top of the sine block is 2 inches tall? (Round the final answer to four decimal places.) The depth of the mill should be 7071.067 inches.
