Problem 4.40

Oxygen gas enters a well-insulated diffuser at 30 lbf/in.2 , 4408R, with a velocity of 950 ft/s through a flow area of 2.0 in.2 At the exit, the flow area is 15 times the inlet area, and the velocity is 25 ft/s. The potential energy change from inlet to exit is negligible. Assuming ideal gas behavior for the oxygen and steady-state operation of the diffuser, determine the exit temperature, in 8R, the exit pressure, in lbf/in.2 , and the mass flow rate, in lb/s.

Step-by-Step Solution:
Step 1 of 3

Elements of Statistics – Chapter 6 Notes Key Points  Density Curves  Normal Distribution  Standard Normal Curve  Standard Normal Table Density Curve  A fitted curve in regard to distribution  Is ALWAYS ON or ABOVE the horizontal axis  Total area under a density curve is always equal to 1 o Density Histogram To determine the density of a class, take the relative frequency and divide by the width of class. AREA = DENSITY x WIDTH Normal Distribution  A variable is “normally distributed” if its distribution has the shape of a symmetric curve. o Characterized by its Mean, , and a Standard Deviation, o The Mean
