When you plot the S_11 for the quarter-wave transformer matching network, you should see additional frequencies at which the load is matched to the source. Why is that happening

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Which of the following controllers anticipates the future from the slope of errors over time? a)-proportional b)-on/off c)-integral d)-derivative.

Steam enters a converging nozzle at 3.0 mpa and 500°c with a at 1.8 mpa. for a nozzle exit area of 32 cm2, determine the exit velocity, mass flow rate, and exit mach number if the nozzle: negligible velocity, and it exits (a) is isentropic (b) has an efficiency of 94 percent
