The air mass flow rate of a jet engine is 10 kg/s. The
stagnation enthalpy at the exit of the turbine is 918 kJ/kg and the
excess air is 4.5.
(a) What should be the mass flow rate of fuel injected in the
afterburner, such that the stagnation enthalpy at the end of the
afterburner is 1700 kJ/kg?
(b) What is the excess air in the afterburner?
(c) What is the maximum temperature in the afterburner?

a 0.16 kg mass at the top of a 0.8 m high (vertical) incline. if
this mass were a uniform, solid sphere (radius .057 m, like a
billiard ball) and it is allowed to roll (without slipping) down
the incline, what will be its speed (in m/s) at the bottom of the
incline?

A soccer ball (mass = 0.450 kg, diameter = 0.70 m) is rolled
down a 3.0 m high ramp that makes an angle of 30 degrees with the
horizontal and is 6.0 m long. Assume the ball is a hollow sphere (I
= 2/3MR^2) and begins at rest. How long (in seconds) would it take
the ball to reach the bottom of the ramp?

An industrial gas turbine operates at an 8.8:1 pressure ratio
and a mass flow of 77 kg/s. The
exhaust temperature is at 437?C and the inlet temperature to the
machine is around 1000?C.
The machine is to be designed for a constant axial velocity of 200
m/s. (This data is based on
the Rolls-Royce Avon, an engine that dates from the 1950s but is
still used as low efficiency
high reliability engine for stationary power such as pipeline
pumping.)
