Air enters an adiabatic turbine at 900 K and 1000 kPa. The air exits at 400 K and 100 kPa with a velocity of 30 m/s. Kinetic and
potential energy changes are negligible. If the power delivered by the turbine is 1000 kW. Required:
a. Find the mass flow rate.
b. Find the diameter of the duct at the exit.
electric current refers to directional negative-to-positive electrons from one atom to the next. Liquid conductors and gas conductors, electric current refers to electrons and protons flow in the opposite direction.
