Other things being equal (including identical heat transfer surfaces), a multipass cross-counterflow

Other things being equal (including identical heat transfer
surfaces), a multipass cross-counterflow heat exchanger designed for a
particular set of specifications (i.e., given “, C*, flow rates, and flow
lengths) will have a shorter noflow (stack) height dimension than a single-pass
crossflow heat exchanger.

(a) It depends on the surface geometries. (b) true (c) false

(d) It depends on the capacity rate ratio.
