Capital costs are influenced by the size of the heat exchanger (i.e., the evaporator and the condenser). Large UA value heat exchangers cost more than lower UA value heat exchangers. You are limited to the UA values specified in the table below. Equations for computing the overall heat transfer coefficients (UA) for the evaporator and the condenser are provided after the table. UA limits (kW/C) on evaporator and condenser vary based on the working/operating fluid. (Note, these numbers are subject to change.) Ammonia Isobutane n-butane UA max limit on evaporator 385 375 690 UA max limit on condenser 3500 7600 4450 1. As a first step, generate first law equations, on a per mass flow rate basis, for each of the components in an ideal, standard Rankine cycle. 2. Determine an appropriate evaporator pressure and an appropriate condenser pressure for an ideal, standard Rankine cycle with the working fluid your team has been assigned: (ammonia, isobutane, n-butane). You are encouraged to start with pressures based on P-h diagrams for the working fluid your team has been assigned.
