Question

Air expands in an adiabatic gas turbine at 1300 kPa and 773 K to 100 kPa and 400 K. Air enters the turbine through a 0.2-m2 cross-sectional area opening with an average velocity of 40 m/sec, and exhausts through a 1-m2 opening.


Determine

a. the mass flow rate of air through the turbine (46.9 kg/s)

b. the power produced by the turbine in kW.    (18300 kW)

Answer 2

A simple garden syringe used to produce a jet of water consist of a piston of area 4cm² which moves in horizontal cylinder which has a small hole of area 4mm² at its ends. If the force on piston is 50N, calculate the value of the speed at which the water is forced out of the small hole, assume the speed of the Pistons negligible
