QUESTION $1$

Steam initially at $2\mathrm{.}8$ MPa and $441$ C is expanded adiabatically and reversibly to $0\mathrm{.}1$ MPa $.$ Compute the pump work $(\frac{J}{g})$ of a Rankine cycle operating with this turbine.

Express your answer as a fraction, not a percentage.

QUESTION $2$

An OVC operates with $314$ K exiting the condenser and $194$ K in the evaporator. The operating fluid is propane. You may afs the compressor is adiabatic and re

versible. Compute the coefficient of performance $($COP$)$ of a comparable Carnot cycle.

QUESTION $3$

Consider N $2$ at $318$ K and $1\mathrm{.}3$ bar in an insulated continuous compressor. The pressure is reversibly increased by a factor of $2\mathrm{.}6.$ Compute W $(k\frac{J}{m}ol).$

QUESTION $4$

Steam initially at $10$ MPa and $355$ C is expanded adiabatically and reversibly to $0\mathrm{.}9$ MPa $.$ Compute the $QH(\frac{J}{g})$ of a Rankine cycle operating with this turbine.

QUESTION $5$

Steam initially at $10$ MPa and $405$ C is expanded adiabatically and reversibly to $0\mathrm{.}3$ MPa $.$ Compute the thermal efficiency of a Rankine cycle operating with this turbine.

Express your answer as a decimal fraction, not a percentage.
