$$1 - \sqrt {{{{R_i}} \over {{R_0}}}} $$
B
$$\sqrt {1 - {{{R_i}} \over {{R_0}}}} $$
C
$$1 - {\left( {{{{R_i}} \over {{R_0}}}} \right)^{1/3}}$$

Consider a parallel-flow heat exchanger with area $${A_p}$$ and a counter-flow heat exchanger with area $${A_c}.$$ In both the heat exchangers, the hot stream flowing at $$1$$ $$kg/s$$ cools from $$80{}^ \circ C$$ to $$50{}^ \circ C$$. For the cold stream in both the heat exchangers, the flow rate and the inlet temperature are $$2$$ $$kg/s$$ and $$10{}^ \circ C$$, respectively. The hot and cold streams in both the heat exchangers are of the same fluid. Also, both the heat exchangers have the same overall heat transfer coefficient. The ratio $${A_c}/{A_p}$$ is ______________
