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 heliocentric and the geocentric models of the solar system included these central principles

During the apollo moon missions, astronauts were concerned about the effects of newton's third law of motion when: o a. they ejected waste water, because they were concerned that it would push them off course. o b. they reentered earth's atmosphere, because they were carrying heavy moon rocks. o c. they took off from earth, because a large force was required to generate large acceleration. o d. they detected incoming space debris, because the inertia of the debris could damage their ship.

The stopwatch used by a student to measure velocity of a pulse in a slinky was of least count 0.1 second. he stops the stopwatch when a pulse has made 3 journeys from one end to the other of the slinky. he finds the seconds hand to be at 52nd division. calculate the correct time noted by him.
