Mixing of two ideal-gas streams, 

(a) Calculate the resulting velocity, temperature, and pressure when the following two air streams are mixed in an apparatus such as that described in Example 15.3-2. The heat capacity C_p of air may be considered constant at 7.0 Btu/lb-mole ∙ F. The properties of the two streams are:

(b) What would the calculated velocity be, if the flow were treated as isothermal and incompressible? 

(c) Estimate E_v, for this operation, basing your calculation on the results of part (b).
