Air flows through an open system at the steady mass flow rate of 5 kg/s. At inlet the air velocity is negligible, the pressure is 1 bar and the
temperature is 15 °C. The air flow is compressed isentropically and
leaves the system at a pressure of 5 bar through a pipe with an internal
diameter of 80 mm. (Assume for air, R=287 J/kgK and y = 1.4).
Calculate:
i. The temperature of the air as it leaves the system.
ii. The velocity in the exit pipe.
iii. The power input to the air.

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.

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