A convergent–divergent nozzle through which air flows is designed to generate Mach 2.2. The supply reservoir pressure is 2.2 MPa and the flow is discharged into ambient air at a pressure of 101 kPa. Under these conditions, the nozzle will be underexpanded, and as a result, expansion waves will exist at the nozzle exit. Find the flow direction just downstream of the exit plane expansion waves under these conditions. What effect does the presence of the expansion waves have on the net axial thrust produced by the nozzle?

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?

Which process is represented by the pv diagram? a. the isobaric process b. the isovolumetric process c. the isothermal process d. the adiabatic process

Africtionless piston-cylinder contains 50 l of saturated liquid r-134a. the piston has a mass and an area resulting in an applied pressure of 500 kpa on the refrigerant. the refrigerant is now heated until its temperature rises to 70∘c. calculate the work (in kj) done during this process.
