the condenser pressure is 10 kPa. If the intermediate pressure is 4 MPa
and the steam enters the low-pressure stage turbine at 600 oC, determine
the following:
(a) Enthalpy at the end of each process
(b) Heat added
(c) Heat rejected
(d) Work of pump and turbines
(e) Thermal efficiency of this cycle.

Consider a steam power plant operating on a simple ideal Rankine
cycle in which the steam enters the turbine at 3 MPa and 350C and
is condensed in the condenser at 75 kPa. Determine the thermal
efficiency of this cycle and sketch an appropriately labeled T-s
diagram. Also compare this thermal efficiency to that a Carnot heat
engine operating between these same two limits.
The change in enthalpy across the pump = work done by the pump:
h2-h1= v1(P2– P1)

5. Does the accuracy of a kNN classifier using the Euclidean
distance change if you (a) translate the data
(b) scale the data (i.e., multiply the all the points by a
constant), or (c) rotate the data? Explain.
Answer the same for a kNN classifier using Manhattan
distance.
