1. Consider a steam turbine in which the steam expands adiabatically. If the turbine consumes 1.00 kg steam each second and the steam is initially at 500 degrees celcius and 20 atmospheres, calculate:
(a) the temperature of the steam at the exhaust.
(b) the maximum power output of the turbine.
(c) the maximum efficiency of the turbine.
2. An engine is constructed using an ideal monatomic gas which is taken through the cycle shown below.
