Air flows through an adiabatic turbine that is in steady operation. the air enters at 150 psia, 900of, and 350 ft/s and leaves at 20 psia, 300of, and 700 ft/s. the inlet area of the turbine is 0.1 ft2. determine the mass flow rate of the air and the power output of the turbine.[20]2.

The process in which the nucleus of an atom splits into two lighter atoms, releasing a large amount of energy is nuclear

Copper has free electrons per cubic meter. a 71.0-cm length of 12-gauge copper wire that is 2.05 mm in diameter carries 4.85 a of current. (a) how much time does it take for an electron to travel the length of the wire? (b) repeat part (a) for 6-gauge copper wire (diameter 4.12 mm) of the same length that carries the same current. (c) generally speaking, how does changing the diameter of a wire that carries a given amount of current affect the drift velocity of the electrons in the wire?
