(a) To generate steam at \(60 \mathrm{~atm}\), two processes are proposed:

(1) Vaporize water at \(1 \mathrm{~atm}\) and compress the steam at \(60 \mathrm{~atm}\).

(2) Pump water to \(60 \mathrm{~atm}\) followed by vaporization.

Which process is preferred? Why?

(b) In a distillation tower, under what circumstances is it desirable to use a partial condenser?
